Koh Chang Guide: Thailand's Underrated Eastern Island

While most travelers flock to Koh Samui, Koh Phangan, and Phuket, Koh Chang remains one of Thailand's best-kept secrets. Thailand's second-largest island, located just 300 kilometers east of Bangkok in Trat Province, offers pristine beaches, jungle-covered mountains, and a refreshingly laid-back atmosphere that mass tourism hasn't yet overwhelmed. With 70% of the island still covered in rainforest and dozens of unspoiled nearby islands within the Koh Chang Marine National Park, this is where you go when you want Thailand's island magic without the crowds.

1. Why Koh Chang Is Thailand's Underrated Gem

When we first visited Koh Chang, we were struck by how quiet the beaches felt compared to the southern islands we'd explored. Despite being Thailand's second-largest island, Koh Chang has managed to remain relatively undeveloped—a rare achievement in modern Thailand. The island stretches approximately 30 kilometers long and 14 kilometers wide, covering roughly 217 square kilometers, with the Koh Chang Marine National Park encompassing an additional 650 square kilometers of protected waters.

The island's slow tourism development is intentional. Unlike the overdeveloped resort islands to the south, Koh Chang has resisted mass commercialization. You won't find the same party atmosphere as Koh Phangan or the shopping malls of Phuket. Instead, you'll find genuine Thai hospitality, affordable prices, and an island that still feels like a discovery rather than a destination.

Who Should Visit Koh Chang?

Koh Chang suits travelers seeking:

• Peaceful beaches without the party crowd
• Family-friendly activities and calm waters
• Budget-conscious travel with excellent value
• Jungle exploration and nature-based adventures
• A mix of relaxation and adventure in one place

The Island's Natural Appeal

The island's rainforest interior is home to native birds, snakes, deer, and even a small population of wild elephants (hence the name "Koh Chang"—Elephant Island). The western coastline, where most tourists stay, features a single road connecting the main beaches and villages, making navigation simple and keeping the island feeling intimate.

2. Getting to Koh Chang: Transport Options

Reaching Koh Chang from Bangkok is straightforward, though it requires a combination of transport methods. The journey takes 5–7 hours total, depending on your chosen route and ferry timing.

Bus + Ferry (Most Popular & Affordable)

The most common route is a bus from Bangkok to Trat Province, followed by a ferry to the island. During our time in Thailand, we found this method to be reliable and budget-friendly. Use our Bangkok public transport guide to reach the Eastern Bus Terminal at Ekamai. Buses depart multiple times daily, with the journey taking approximately 5–6 hours. Fares typically range from 250–400 THB ($7–11 USD) depending on the bus class.

From Trat, you'll take a minibus or shared songthaew (approximately 50 THB / $1.50 USD) to Laem Ngop pier, where ferries depart for Koh Chang. The ferry crossing takes 45 minutes to 1 hour and costs 100–150 THB ($3–4 USD) per person. Ferries run regularly throughout the day, with the last departure typically around 4–5 PM.

Transport Tips:

• Peak season ferries: Book your ferry in advance during December–February
• Ferry schedules: Ferries run less frequently during the rainy season (May–October)
• Direct minibus services: Some Bangkok hotels offer direct minibus-to-ferry packages for 400–600 THB ($11–16 USD)
• Early morning departures: Leave Bangkok before 8 AM to arrive on the island by early afternoon

Flying to Trat (Fastest Option)

Bangkok Airways operates flights from Bangkok to Trat Airport, which is just 15 minutes from the Laem Ngop ferry terminal. Flight time is approximately 1 hour, and fares typically range from 1,500–3,000 THB ($42–85 USD) depending on how far in advance you book. This option is ideal if you're short on time or prefer to avoid long bus journeys.

3. Best Beaches on Koh Chang

Koh Chang's western coastline features several distinct beach areas, each with its own character. The main tourist beaches are connected by a single coastal road, making it easy to explore and find your preferred vibe.

Hat Sai Khao (White Sand Beach)

Hat Sai Khao is the island's longest and most popular beach, stretching for several kilometers along the northern coast. The sand is genuinely white and fine, the water is calm and clear, and the beach is lined with a mix of budget bungalows, mid-range resorts, and upscale hotels. When we visited, we found the beach busy but not crowded—a comfortable middle ground between isolation and social atmosphere.

This beach is ideal for families and travelers seeking a balance of amenities and natural beauty. The northern end near the pier is more developed with restaurants and shops, while the southern end remains quieter and more relaxed. Water sports are available here, including kayaking and paddleboarding.

Hat Kai Muk (Egg Beach)

Named for the smooth, egg-shaped rocks scattered along the shore, Hat Kai Muk is a smaller, more intimate beach located south of Hat Sai Khao. The beach is sheltered and perfect for swimming, with shallow, calm waters ideal for families with young children. The atmosphere is noticeably quieter than Hat Sai Khao, with fewer tourists and a more local feel.

Accommodation here ranges from simple wooden bungalows to comfortable mid-range resorts, with prices generally lower than the main beach. In our experience, this beach offers the best balance of accessibility and tranquility.

Hat Ta Nam (Lonely Beach)

Despite its name, Hat Ta Nam isn't actually lonely—it's simply smaller and more laid-back than the northern beaches. Located further south, this beach attracts a younger, more adventurous crowd and is known for its relaxed beach bars and social atmosphere. The beach is rockier than Hat Sai Khao, but the water is clear and excellent for snorkeling.

Hat Ta Nam is the best choice if you want a beach with a community vibe, affordable accommodation, and easy access to jungle activities and waterfall hikes.

Laem Bang Bao (Bang Bao Pier Village)

Laem Bang Bao is technically not a beach but a working fishing pier village at the southern tip of the island. However, it's one of Koh Chang's most atmospheric locations. The pier is lined with wooden houses built over the water, seafood restaurants, and tour operators. This is where you'll arrange snorkeling trips, diving expeditions, and visits to nearby islands.

The area has a distinctly Thai character—you'll see local fishermen, longtail boats, and a genuine working harbor rather than a tourist-focused beach. In our experience, spending an evening here watching the sunset and eating fresh seafood is one of the island's best experiences.

Beach Comparison:

Beach	Best For	Vibe	Accommodation
Hat Sai Khao	Families, all travelers	Busy but comfortable	Budget to luxury
Hat Kai Muk	Families, swimmers	Quiet, sheltered	Budget to mid-range
Hat Ta Nam	Young travelers, social	Relaxed, community-focused	Budget to mid-range
Laem Bang Bao	Foodies, boat tours	Authentic, working harbor	Mid-range to luxury

4. Water Activities: Snorkeling, Diving & Island Hopping

The waters surrounding Koh Chang are remarkably clear and teeming with marine life, making it one of Thailand's best destinations for diving and snorkeling. The Koh Chang Marine National Park protects dozens of nearby islands, each offering unique underwater experiences.

Snorkeling

Snorkeling is the most accessible water activity, requiring no certification and minimal equipment. The coral reefs surrounding Koh Chang and nearby islands are healthy and colorful, home to tropical fish, rays, and occasionally sea turtles. Most snorkeling trips depart from Laem Bang Bao and cost 500–800 THB ($14–22 USD) per person for a half-day trip.

Popular snorkeling destinations include:

• Koh Rang: The most pristine island in the national park, with excellent coral and clear water
• Koh Wai: A smaller island with calm, shallow waters ideal for beginners
• Koh Kradat: Known for its white sand beach and abundant fish

Scuba Diving

Koh Chang has several dive shops offering PADI certification courses and guided dives. The dive sites range from shallow coral gardens suitable for beginners to deeper reefs with pelagic fish. Popular dive sites include Hin Lad Reef and the wreck of the HTMS Khram, a former Thai naval vessel. For more advanced diving in Thailand, the Similan Islands and Koh Tao are worth planning into your trip.

Certification courses (Open Water) cost approximately 9,000–12,000 THB ($250–330 USD) and take 3–4 days. Guided dives for certified divers cost 1,500–2,500 THB ($42–70 USD) per dive, depending on the site and group size.

Island Hopping

The easiest way to explore multiple islands is to book a longtail boat tour from Laem Bang Bao. These tours typically visit 3–4 islands in a day, include snorkeling stops, and cost 600–1,000 THB ($17–28 USD) per person. Tours usually include lunch and snorkeling equipment.

During our time exploring the islands, we found that private longtail boat rentals (2,000–3,000 THB / $56–85 USD per boat for a full day) offer more flexibility if you're traveling with a group.

5. Jungle Adventures: Waterfalls, Hiking & Wildlife

Beyond the beaches, Koh Chang's interior rainforest offers excellent opportunities for hiking, waterfall exploration, and wildlife spotting. If jungle trekking excites you, also consider a day trip to Khao Yai National Park, Thailand's first UNESCO-listed park, just a few hours from Bangkok. The island's elevation reaches approximately 743 meters at its highest point, providing scenic viewpoints and diverse ecosystems.

Klong Plu Waterfall

The most accessible waterfall on the island, Klong Plu is a multi-tiered cascade located near Hat Sai Khao. The hike takes approximately 30–45 minutes through jungle terrain and is suitable for most fitness levels. The waterfall pools are refreshing for swimming, and the surrounding forest is home to native birds and butterflies.

Entrance to the waterfall area costs 20 THB ($0.50 USD), and no guide is necessary—the trail is well-marked. In our experience, visiting early in the morning (before 9 AM) means you'll have the waterfall largely to yourself.

Jungle Trekking & Guided Tours

Several tour operators on the island offer guided jungle treks ranging from 2–6 hours. These treks explore the island's interior, passing through primary rainforest and offering opportunities to spot wildlife including deer, monitor lizards, and occasionally wild elephants (though sightings are rare).

Popular jungle activities:

• Guided jungle trek: 800–1,500 THB ($22–42 USD) per person
• Waterfall and swimming tour: 600–1,000 THB ($17–28 USD) per person
• Wildlife spotting tour: 1,000–1,500 THB ($28–42 USD) per person
• Zip-lining through the canopy: 1,200–1,800 THB ($34–50 USD) per person

Khlong Plu Waterfall Trek

For a more immersive experience, the trek to the upper pools of Khlong Plu involves wading through streams and climbing over rocks. The upper pools are less crowded and offer a more authentic jungle experience. Allow 2–3 hours for this trek.

Did You Know? Koh Chang is home to a small population of wild Asian elephants, though they're rarely seen by tourists. The island's name, "Koh Chang," literally means "Elephant Island" in Thai.

6. Where to Stay: Accommodation for Every Budget

Koh Chang offers excellent accommodation options across all price ranges, from basic backpacker bungalows to luxury beachfront resorts. Most accommodation is concentrated along the western beaches, with Hat Sai Khao and Hat Kai Muk offering the widest selection. For help budgeting your stay, our Thailand daily costs guide for 2026 breaks down typical expenses island by island.

Budget Accommodation (500–1,500 THB / $14–42 USD per night)

Budget bungalows and hostels are scattered across all the main beaches. These typically offer basic but clean rooms, often with shared bathrooms and minimal amenities. Many budget properties are family-run and offer a genuine local experience.

Budget options include:

• Basic bungalows: Simple wooden or concrete structures with fan cooling
• Hostels: Shared dorm rooms with communal areas, popular with backpackers
• Guesthouses: Small, family-owned properties with 5–10 rooms

Mid-Range Accommodation (1,500–3,500 THB / $42–97 USD per night)

Mid-range hotels and resorts offer comfortable rooms with air conditioning, private bathrooms, and basic amenities like WiFi and restaurant service. Many are beachfront or beach-adjacent, with small pools and friendly staff.

During our stays in this category, we found excellent value—comfortable, clean rooms with good service at reasonable prices. This is where most travelers find their sweet spot on Koh Chang.

Luxury Accommodation (3,500+ THB / $97+ USD per night)

Luxury resorts have proliferated on Koh Chang in recent years, catering to well-to-do Thai and international travelers. These properties offer upscale amenities including spa services, fine dining restaurants, private beaches, and personalized service.

Luxury amenities typically include:

• Beachfront locations with private beach access
• Spa and wellness services offering traditional Thai massage
• Multiple restaurants with international and Thai cuisine
• Swimming pools and water sports facilities
• Concierge services for activity bookings and transportation

7. Food & Dining: Fresh Seafood & Thai Cuisine

Koh Chang's dining scene reflects the island's character—fresh, affordable, and authentically Thai. The best seafood restaurants are concentrated at Laem Bang Bao, where you can watch fishing boats unload the day's catch while you eat. For broader Thai food background, our guides on Thai street food and Thai curry varieties are worth a read before you arrive.

Seafood at Laem Bang Bao

The pier village is the island's culinary heart. Wooden restaurants built over the water serve grilled fish, prawns, squid, and crab at prices that would seem impossible elsewhere. A full meal of grilled fish with rice and vegetables typically costs 150–300 THB ($4–8 USD).

In our experience, the best approach is to point at the fresh catch displayed on ice and ask the restaurant to grill it for you. Arrive around 5–6 PM to watch the sunset while eating fresh seafood.

Beach Shack Dining

Along Hat Sai Khao and Hat Kai Muk, casual beachfront restaurants serve a mix of Thai and Western food. These range from simple open-air shacks to more established beach bars. You'll find pad thai, green curry, fresh fruit smoothies, and cold beer at very reasonable prices.

Typical beach meal prices:

• Pad Thai or stir-fried noodles: 60–100 THB ($1.70–2.80 USD)
• Curry with rice: 80–120 THB ($2.25–3.35 USD)
• Fresh fruit smoothie: 40–60 THB ($1.10–1.70 USD)
• Beer: 50–80 THB ($1.40–2.25 USD)

Local Markets

The island has small local markets (most active in the morning) where you can buy fresh fruit, snacks, and basic groceries. These markets offer authentic Thai food experiences and are frequented by locals rather than tourists.

Did You Know? Thai cuisine varies significantly by region. The eastern region near Koh Chang features dishes influenced by Cambodian cuisine, including more use of fresh herbs and lighter preparations compared to the heavier curries of central Thailand.

8. Best Time to Visit: Seasons & Weather

Koh Chang's tropical climate means warm weather year-round, but the island experiences distinct wet and dry seasons that affect your experience. Our best time to visit Thailand guide and rainy season travel tips cover all regions including the eastern coast.

High Season (November to February)

The cool and dry season is the island's peak tourist season. Temperatures range from 25–30°C (77–86°F), rainfall is minimal, and the sea is calm and clear. This is the best time for water activities, hiking, and beach relaxation. However, accommodation fills quickly and prices are at their highest.

During our November visit, we found the weather perfect—sunny days, cool evenings, and calm seas ideal for snorkeling and island hopping.

Shoulder Season (March to May & September to October)

These months offer good weather with fewer tourists and lower prices. March to May is hot (30–35°C / 86–95°F) but still dry, while September to October marks the transition into the rainy season with occasional showers but still many sunny days.

Low Season (June to August)

The rainy season brings frequent afternoon showers and occasional storms. The sea can be rough, making water activities less reliable. However, the island is lush and green, accommodation is cheap, and you'll have beaches largely to yourself. This season suits budget travelers and those seeking solitude over perfect weather.

Seasonal Comparison:

Season	Weather	Crowds	Prices	Best For
Nov–Feb	Dry, cool, perfect	High	High	All activities
Mar–May	Hot, dry	Medium	Medium	Beach lovers
Jun–Aug	Rainy, humid	Low	Low	Budget travelers
Sep–Oct	Transitional	Low	Low	Adventurous travelers

9. Safety, Practical Information & Getting Around

Koh Chang is very safe by international standards. Violent crime against tourists is virtually non-existent, and petty theft is rare. Standard travel precautions apply—don't leave valuables unattended on beaches, use hotel safes, and be cautious with alcohol consumption. For comprehensive safety information, read our Thailand safety guide for tourists and consider travel insurance before your trip.

Getting Around the Island

The island is small enough to explore easily. The main road runs down the western coast, connecting all the major beaches. Transportation options include:

Motorbike Rental: The most popular option for independent travelers. Rentals cost 150–250 THB ($4–7 USD) per day for a basic automatic scooter. You'll need an International Driving Permit (IDP) or Thai motorcycle license. In our experience, the roads are well-maintained but can be steep and winding in places—ride cautiously.

Shared Songthaew: Red shared minibuses run along the main road throughout the day, costing 20–50 THB ($0.55–1.40 USD) per journey. These are reliable and cheap but operate on flexible schedules.

Taxis & Private Drivers: Taxis aren't metered on the island, but you can negotiate fares. A ride from Hat Sai Khao to Laem Bang Bao costs approximately 200–300 THB ($5.60–8.40 USD). Many hotels can arrange private drivers for longer trips.

Money & Costs

The island has ATMs at Hat Sai Khao and near the pier, dispensing Thai Baht. Credit cards are accepted at mid-range and upscale establishments, but budget accommodations and small restaurants prefer cash. The island is very affordable—a comfortable day (meals, activities, accommodation) costs 1,000–2,000 THB ($28–56 USD) on a budget.

Internet & Connectivity

WiFi is available at most hotels and restaurants, though speeds can be slow. For reliable internet, consider getting a Thailand eSIM or local SIM card. Major Thai providers (AIS, Dtac, True Move) have shops at Hat Sai Khao and offer affordable data plans.

10. Day Trips & Nearby Islands Worth Visiting

While Koh Chang itself offers plenty to do, the surrounding Koh Chang Marine National Park includes dozens of smaller islands, each with unique characteristics. For a full Thailand island hopping guide covering all regions, we break down the best multi-island routes across the country.

Koh Rang (The Best Island)

Koh Rang is the crown jewel of the national park—a pristine island with white sand beaches, clear turquoise water, and excellent snorkeling. The island is less developed than Koh Chang, with only a few basic bungalows and a national park ranger station. A day trip costs 600–800 THB ($17–22 USD) and includes snorkeling and lunch.

In our experience, Koh Rang offers the closest thing to an untouched island experience in this region. The coral is healthy, fish are abundant, and the beaches are genuinely beautiful.

Koh Wai (Family-Friendly)

Koh Wai is smaller and more sheltered than Koh Rang, with calm, shallow waters perfect for families and beginner snorkelers. The island has a few simple bungalows and restaurants, making it suitable for an overnight stay if you want to experience island life beyond Koh Chang.

Koh Kradat (Beach & History)

Koh Kradat features a beautiful white sand beach and the ruins of an old Japanese military base from World War II. The island is less crowded than Koh Rang and offers good snorkeling plus a bit of history.

Koh Mak (Alternative Base)

Koh Mak is another island in the national park, slightly larger than Koh Wai and less touristy than Koh Chang. Some travelers prefer to base themselves here for a quieter experience, though it has fewer restaurants and activities than Koh Chang.

Island Hopping Costs:

• Half-day snorkeling tour: 500–800 THB ($14–22 USD)
• Full-day island tour: 800–1,200 THB ($22–34 USD)
• Private longtail boat rental: 2,000–3,000 THB ($56–85 USD) for 4–6 people

Is Koh Chang suitable for families with young children?

Absolutely. The calm waters at Hat Kai Muk and Hat Sai Khao are ideal for young swimmers. The island has good medical facilities, family-friendly accommodation, and activities suitable for all ages. The main challenge is the heat—bring plenty of sunscreen and stay hydrated.

Bring sunscreen (SPF 50+), a hat, lightweight clothes, swimwear, reef-safe sunscreen for snorkeling, and a light rain jacket for occasional showers. Insect repellent is useful, especially during the rainy season. The island has shops for forgotten items, though prices are higher than in Bangkok.

Is it possible to visit Koh Chang without a motorbike?

Yes. Shared songthaews run along the main road, and hotels can arrange transportation. However, having a motorbike gives you more freedom to explore at your own pace. If you're uncomfortable riding, negotiate a daily rate with a local driver (approximately 1,000–1,500 THB / $28–42 USD per day).
