Koh Samui Beaches

  • DurationMulti-day
  • AdmissionAdult Free · Child Free

Koh Samui is Thailand's second-largest island, covering 228 square kilometres in the Gulf of Thailand off the coast of Surat Thani Province. A ring road circles the island, connecting a series of distinct beaches that cater to markedly different travel styles. Chaweng Beach on the east coast is the longest and most developed stretch — 8 kilometres of sand backed by a concentrated strip of hotels, restaurants, bars, and nightclubs that stay active until 2–3 am.

Thailand's second-largest island featuring palm-fringed beaches ranging from party-central Chaweng to serene Lamai and family-friendly Bophut. Each beach offers distinct character, from luxury resorts to backpacker bungalows, with year-round warm waters.

Koh Samui is Thailand's second-largest island, covering 228 square kilometres in the Gulf of Thailand off the coast of Surat Thani Province. A ring road circles the island, connecting a series of distinct beaches that cater to markedly different travel styles. Chaweng Beach on the east coast is the longest and most developed stretch — 8 kilometres of sand backed by a concentrated strip of hotels, restaurants, bars, and nightclubs that stay active until 2–3 am. Lamai Beach, 5 kilometres south of Chaweng, has a similar hotel-and-bar infrastructure but on a smaller scale and with a lower-key atmosphere. Bophut, on the north coast, clusters around a restored Sino-Portuguese fishing village known as Fisherman's Village, where independent restaurants and boutique guesthouses occupy old wooden shophouses; a Friday night walking street market fills the main road. Mae Nam, further west along the north coast, is Samui's longest stretch of fine sand with far fewer tourists than Chaweng. Maenam and Lipa Noi on the west coast face the setting sun and offer the best sunset views on the island. Inland, the 18-metre Big Buddha at Wat Phra Yai in the northeast and Grandfather and Grandmother Rocks (Hin Ta and Hin Yai) on the south coast near Lamai are popular side trips. Samui has its own international airport (USM) with direct flights to Bangkok, Kuala Lumpur, and several European hub airports via Singapore.

When to visit

February through April and June through August offer dry, sunny conditions on Koh Samui. Avoid November to mid-January when the Gulf coast receives its monsoon season. Visiting Chaweng on weekday mornings gives the best beach conditions before the day-tripper crowds arrive.

Accessibility

The ring road is paved and accessible by car or scooter. Most main beach areas have paved paths to beach access points, but the sand itself presents challenges for wheelchair users. Several larger resorts at Chaweng and Lamai have built accessible pathways and beach wheelchairs available on request.

Frequently asked questions

Which beach on Koh Samui is best for families?

Maenam and Choeng Mon beaches on the north coast are the best family choices: calmer water, shallower depths near shore, and fewer loud bars than Chaweng. Bophut also suits families well with its village atmosphere and walkable boardwalk.

When is the best season to visit Koh Samui?

Koh Samui's dry season runs from February to August, with peak conditions in March to May. The Gulf of Thailand's weather patterns differ from the Andaman Sea — Samui receives heavy rain in November and December when the Andaman is calm.

Is a scooter or car needed to explore Koh Samui?

A scooter (rent from around 200 baht/day) or car (from 700–1,000 baht/day) is needed to reach the quieter beaches and inland sights. Songthaew shared taxis circle the ring road and cover the main beaches for 50–100 baht per person.
