Khao Yai National Park: The Ultimate Day Trip From Bangkok (2026 Guide)

Why Khao Yai Deserves a Spot on Your Thailand Itinerary

Most visitors to Thailand stick to beaches and temples, but Khao Yai National Park offers something completely different. Established in 1962 as Thailand's very first national park and now a UNESCO World Heritage Site, this 2,168-square-kilometre reserve sits just 2.5 hours northeast of Bangkok, making it one of the easiest nature escapes from the capital. It consistently ranks among the best day trips from Bangkok alongside Ayutthaya and Kanchanaburi.

Compared to Thailand's crowded southern islands, Khao Yai is refreshingly quiet. You will find dense jungle, dramatic waterfalls, wild elephants, gibbons, hornbills and over 300 bird species without fighting for space on a tour boat.

Getting There

The gateway town is Pak Chong in Nakhon Ratchasima province. From Bangkok you can take a minivan from Mo Chit (around 200 baht, roughly two hours) or catch a train to Pak Chong station. Use the Bangkok public transport guide to navigate to the right terminal. From Pak Chong, songthaews and private taxis run to the park's northern entrance at the Chao Por Khao Yai Shrine. A second entrance at Noen Hom on the Prachinburi side is less busy.

If you prefer convenience, many Bangkok tour operators run day trips that include hotel pick-up, a guide and lunch for around 2,000 to 3,500 baht per person.

Entrance Fees and Hours

The park is open daily from 06:00 to 18:00. Foreign visitors pay 400 baht per adult and 200 baht per child. Keep your ticket stub because rangers check it at multiple points inside the park.

Best Things to Do

Waterfalls

Haew Narok is the park's most famous waterfall, plunging 150 metres in three tiers. Haew Suwat, made famous by the Leonardo DiCaprio film The Beach, is an easier walk from the road and perfect for photos. If you enjoy waterfall day trips, the Erawan Falls in Kanchanaburi are another excellent option from Bangkok.

Hiking

Several marked trails range from gentle one-hour loops near the Visitor Centre to full-day treks deep into the jungle. Guided night safari walks are popular for spotting deer, civets and porcupines after dark.

Wildlife

Wild elephants are regularly sighted near the park roads during the cooler months. Great hornbills, gibbons and macaques are common around the campgrounds. Birdwatchers should head out at dawn for the best sightings. If you want to see elephants in a responsible setting, check our guide to ethical elephant sanctuaries in Thailand and wildlife conservation volunteering.

Camping

Two campgrounds are available: Lam Ta Khong near the Visitor Centre and Khao Rom Viewpoint. Tents and sleeping bags can be rented on-site for a few hundred baht. Book ahead on weekends and Thai holidays because spots fill quickly.

Best Time to Visit

The dry season from November to April offers the best weather for hiking and the easiest wildlife spotting, since thinner vegetation makes animals more visible. The rainy season (June to September) is greener and the waterfalls are at full force, but trails can be slippery. Read our full best time to visit Thailand guide and rainy season travel tips before finalising your dates.

Tips for First-Time Visitors

• Wear sturdy shoes and long trousers for jungle trails.
• Bring insect repellent; leeches are common in the wet season.
• Pack a rain jacket even in the dry season because mountain weather changes fast.
• Wheelchair-accessible toilets are available at the Visitor Centre, Chao Por Khao Yai Shrine, Noen Hom Entrance and Haew Suwat Waterfall.

Khao Yai is proof that Thailand has far more to offer than beaches. If you have a spare day in Bangkok, this UNESCO-listed jungle is well worth the trip. Combine it with the nearby Khao Yai food and wine festival for a full weekend escape, or pair your northeast Thailand trip with a stay at Koh Chang on the eastern coast. New to Thailand?
