Koh Samet
Koh Samet is the closest major island to Bangkok, making it the capital's favorite weekend beach escape. Located just 200 kilometers southeast of Bangkok in the Gulf of Thailand, the island is part of Khao Laem Ya - Mu Ko Samet National Park. Its white sand beaches along the eastern coast are consistently sunny thanks to a microclimate that keeps it drier than the mainland, even during monsoon season. While popular with Thai weekenders, the island retains a more local feel than the southern islands and offers excellent beach-hopping along its east coast.

Beaches on Koh Samet
Sai Kaew Beach (Diamond Beach)
The longest and most popular beach on Koh Samet, a 1-kilometer stretch of squeaky-white sand with clear turquoise water. The main hub with beachside restaurants, deck chairs, and nightly fire shows. Gets packed on weekends but quieter on weekdays.
Ao Phai
A smaller beach just south of Sai Kaew with a good mix of budget and mid-range accommodation. The famous Naga Bar and Silver Sand are here, making it popular with younger travelers. Great swimming and a more relaxed vibe than Sai Kaew.
Ao Wong Duan
A beautiful crescent-shaped bay with calm water, popular with Thai families and couples. Less party-oriented than the northern beaches with a more resort-like atmosphere. Water sports including banana boats and jet skis are available here.
Ao Wai
A small, secluded beach on the southern part of the east coast, less developed and quieter than the main beaches. Crystal-clear water and good snorkeling around the rocks at either end. Only one resort and a restaurant operate here.
Ao Phrao (Paradise Beach)
The only developed beach on the west coast, offering stunning sunsets that the east coast beaches miss. Home to two upscale resorts (Le Vimarn and Ao Prao Resort), this beach has a more exclusive feel with excellent dining options.
