The Best Beaches in Koh Samui

Samui's Beach Geography

Koh Samui is Thailand's second-largest island (after Phuket), sitting in the Gulf of Thailand about 35 km off the Surat Thani coast. A ring road circles the island — 51 km total — making it possible to check every beach in a single day on a rented scooter (150-250 baht/day, about $4-7). The east coast has the most developed beaches and nightlife, the north is quieter and more upscale, and the west and south have the least traffic and the best sunsets.

Unlike the Andaman Sea coast (Phuket, Krabi, Phi Phi), Samui's beaches face the sheltered Gulf, which means calmer water and less dramatic tidal variation. The trade-off is that the water isn't as clear as the Andaman side — visibility is decent but not spectacular, and after storms it can turn murky for a day or two.

Bangkok Airways has a near-monopoly on flights to Samui airport, which keeps prices high: expect 3,000-6,000 baht ($85-170) one-way from Bangkok. The budget alternative is flying Nok Air or AirAsia to Surat Thani, then taking a bus-and-ferry combination (about 5-6 hours total, 500-800 baht). Lomprayah and Seatran Discovery run catamaran ferries from Surat Thani's Donsak pier.

Chaweng Beach

The main event. Chaweng is a 7 km strip of pale sand running along Samui's east coast, backed by a road dense with hotels, restaurants, bars, 7-Elevens, and tailors who'll make you a suit in 24 hours. The sand is fine and the water is swimmable year-round, with a gentle gradient that suits families.

The beach itself is genuinely good — wide, well-maintained by the hotels, and long enough to absorb large numbers of people without feeling packed (except during Thai holidays like Songkran in April). The problem, if you want to call it that, is the strip behind it: Chaweng's road is a traffic-clogged corridor of neon, noise, and tourist commerce. This is Thailand's beach tourism machine at full throttle.

Chaweng Costs

• Beachfront sunbed rental: 100-200 baht ($3-6), often free if you order food and drinks from the attached restaurant
• Thai massage on the beach: 300-400 baht ($9-11) for one hour
• Pad thai from a beach vendor: 80-120 baht ($2.30-3.40)
• Hotels range from 800-baht guesthouses on the back streets to the 15,000-baht-per-night Centara Grand at the north end

Chaweng Noi

The southern extension of Chaweng, separated by a rocky headland and noticeably calmer. Chaweng Noi is about 1 km long, with softer sand and fewer beach bars. Several upscale resorts (Vana Belle, New Star Beach Resort) front this stretch, and their maintained beach areas are well-kept. Non-guests can access the public beach between the resorts.

The snorkeling here is marginally better than at Chaweng proper — the rocky headland at the northern end has some coral and tropical fish. Bring your own mask; rental gear on Samui is often in poor condition.

This is one of the reasons Koh Samui Beaches continues to draw visitors year after year.

Lamai Beach

Samui's second beach, about 5 km south of Chaweng. Lamai has a similar setup — long sandy beach, resort-lined road, bars and restaurants — but at a slightly lower intensity and price point. The crowd here skews older and more European, with a strong Scandinavian and German contingent, compared to Chaweng's more mixed demographic.

The beach is divided roughly into three sections. North Lamai has the better sand and water. Central Lamai has the most facilities and nightlife (Lamai's walking street market runs on Sunday evenings, with food stalls, clothing, and souvenirs). South Lamai gets rockier and quieter, ending at the Hin Ta and Hin Yai (Grandfather and Grandmother rocks) — phallic rock formations that are a Samui tourist staple.

Bophut and Fisherman's Village

The north coast has a different character entirely. Bophut's Fisherman's Village is a single street of converted Chinese shophouses, now housing boutique hotels, restaurants, and bars. The beach is narrow and the sand coarser than Chaweng, but the atmosphere is more intimate — couples and older travelers dominate.

Compared to similar options, Koh Samui Beaches stands out for its mix of quality and accessibility.

The Friday Walking Street Market transforms the village road into a dense night market with live music, Thai street food (look for the mango sticky rice stall near the east end — 60 baht for a generous portion), handmade jewelry, and clothing. The market runs from about 5pm to 11pm and is one of the best evening activities on the island.

Bophut faces north toward Koh Phangan, and on full moon nights you can see the glow of the Full Moon Party across the water. Lomprayah fast ferries to Koh Phangan depart from the nearby Nathon pier (30 minutes, 300 baht one-way).

Maenam Beach

West of Bophut, Maenam is a 3 km stretch of golden sand that remains noticeably quieter than the east coast. The beach is wide, the water shallow, and the palm trees provide actual shade — something the more developed beaches have largely lost. Budget accommodation (bungalows for 500-1,500 baht/night) still exists along Maenam, making it the best-value beach area on Samui.

Local travel experts consistently recommend Koh Samui Beaches as a top choice for visitors.

The Chinese temple Wat Na Phra Lan sits at the eastern end of the beach, and the Big Buddha temple (Wat Phra Yai) on its own islet is a 10-minute drive east. Maenam village has a small market, ATMs, and Thai restaurants where a full meal costs 60-100 baht — about a third of what you'd pay on Chaweng.

Silver Beach (Haad Thong Ta Kian)

A small, cove-style beach between Chaweng and Lamai, partially hidden behind the Crystal Bay resort. Silver Beach is only about 300 meters long, framed by granite boulders, with notably clear water and the best on-shore snorkeling on Samui. The rocks at both ends of the beach harbor schools of damselfish, parrotfish, and the occasional sea urchin (watch your feet).

Access is via a steep road through the Crystal Bay and Silver Beach Resort properties. There are two beach restaurants, both overpriced by Samui standards (mains 200-400 baht), but the setting justifies it. The beach is small enough that it fills up by mid-morning in peak season — arrive before 9am for the best spot.

If Koh Samui Beaches is on your list, booking during shoulder season typically delivers the best value.

Lipa Noi

The west coast is Samui's quiet side. Lipa Noi, south of the Nathon ferry pier, is a long, shallow beach that stretches far out at low tide — you can walk 200 meters from shore and the water barely reaches your waist. The sunsets from here are the best on the island, with the silhouette of the Ang Thong Marine Park islands on the horizon.

There's minimal development along Lipa Noi: a few scattered resorts (Lipa Lodge, Nikki Beach Samui at the southern end) and the occasional beachfront restaurant. The lack of infrastructure is the point. This is the beach for people who've done Chaweng and want the opposite.

Practical Information

Rainy Season Timing

Samui's weather pattern differs from Thailand's west coast. The Gulf of Thailand monsoon hits hardest from October to mid-December, with November being the wettest month (heavy rain, rough seas, occasional flooding). The best weather runs from January to April — hot, dry, and with calm seas. May to September is warm with occasional afternoon showers but generally good beach weather. For official planning information, see Tourism Authority of Thailand.

Repeat visitors to Koh Samui Beaches often say the second trip reveals layers they missed the first time.

Full Moon Party Access

Koh Phangan's Full Moon Party happens monthly on Haad Rin beach. Fast boats from Samui run all night on party nights (500-600 baht return). The party draws 10,000-30,000 people depending on the month. If you're staying on Samui and want to attend, book the boat in advance and guard your valuables. If you don't want to attend, the other Phangan beaches are deserted on full moon night — which is its own kind of appeal.

Temple Etiquette

Samui has several important temples. Cover knees and shoulders when visiting. The Big Buddha (Wat Phra Yai) is the most-visited and most photographed. Wat Plai Laem, nearby, has an 18-armed Guanyin statue and koi ponds. Both are free to enter, though donations are expected.

Food Worth Seeking Out

• Laem Din Market (Chaweng): Night market with dozens of food stalls. Grilled squid, som tam (papaya salad), khao man gai (chicken rice) — all 50-80 baht
• Nathon morning market: Fresh fruit, Thai sweets, and coffee. Most items 20-50 baht
• South Lamai seafood restaurants: Choose your fish from the ice display, pay by weight. A whole grilled sea bass runs 250-400 baht
