Overview
Lamai Beach is Koh Samui’s second-largest beach — a 4 km stretch along the southeast coast that hits the sweet spot between lively and laid-back. While Chaweng draws the party crowds and package tourists, Lamai attracts couples, digital nomads, Muay Thai enthusiasts, and travelers who want a real Thai beach experience at 10-20% lower prices.
The south end holds Samui’s most photographed natural landmark: Hin Ta Hin Yai (the Grandfather and Grandmother Rocks), granite formations shaped by centuries of erosion into unmistakably suggestive forms. The central strip buzzes with restaurants, massage shops, and bars. The north end offers quiet snorkeling among rocky outcrops.
Lamai also has something Chaweng doesn’t: the island’s oldest and best Muay Thai training camps, a vibrant Sunday night market, and some of Samui’s most affordable coworking spaces.
Key facts: 4 km long · Southeast coast · Golden sand · Hin Ta Hin Yai rocks · Muay Thai camps · Sunday night market · 25 min from airport · 10-20% cheaper than Chaweng
The Three Sections
Lamai divides into three distinct zones, each with its own character.
North Lamai (~2 km)
The quietest section — a winding beach line punctuated by rocky outcrops. More secluded, popular with couples and families seeking peace. The rocks create natural pools and coves that offer Lamai’s best snorkeling. Luxury resorts (Banyan Tree, Renaissance) cluster here.
Central Lamai (~1 km)
The busiest strip, running from the Lamai river to roughly Aloha Resort. This is where the restaurants, bars, shops, and nightlife concentrate. The beach is widest here with the calmest, clearest water — the best swimming conditions. Most mid-range accommodation is within walking distance.
South Lamai (~600 m)
The dramatic end. The beach narrows from ~40 meters down to ~15 meters as it approaches the famous Hin Ta Hin Yai rocks. Rocky scenery, granite boulders, and good snorkeling around the formations. The viewpoint above the rocks is a popular sunset spot.
Hin Ta Hin Yai — Grandfather and Grandmother Rocks
Samui’s most famous natural landmark sits at Lamai’s southern tip — two granite rock formations sculpted by wind and waves into shapes that unmistakably resemble male and female anatomy. Hin Ta (Grandfather Rock) is the male form; Hin Yai (Grandmother Rock) is the female.
The legend
According to local folklore, an elderly couple named Ta Kreng and Yai Riem from Nakhon Si Thammarat province set sail to arrange a marriage for their son. A violent storm seized their boat, and they drowned. Their bodies turned to stone as proof of their devotion — a symbol of eternal love that locals still honor.
Visiting
- Open daily — no gate, technically accessible anytime (official hours: 8:30 AM-6:30 PM)
- Free admission — parking 10 THB for scooter
- Souvenir stalls and food vendors line the path to the rocks
- Best for photos: Morning or late afternoon for softer light
- Walk carefully on the wet rocks near the formations
The rocks are a fertility symbol — locals visit to pray for blessings in relationships and childbearing.
Muay Thai
Lamai is the Muay Thai capital of Koh Samui. The area has the island’s oldest and most respected training camps, plus regular stadium fights that range from tourist-friendly to genuinely professional.
Training camps
- Lamai Muay Thai Camp (WMC): Samui’s oldest camp, operating since 1998. WMC-sanctioned with world champion Thai trainers. All levels from absolute beginner to professional fighter. ~12,000 THB/week, ~40,000 THB/month. On-site accommodation available.

Undercard bouts often feature tourist fighters who trained for a week and took the challenge. Main events showcase professional Thai boxers. The atmosphere is electric — drums, shouting, gambling, beer.
Lamai Night Market
Lamai has two market experiences:
Sunday Walking Street
Every Sunday on Had Lamai Road. Stalls set up from late afternoon — arrive around 5 PM for the best selection. More artisanal and local than Chaweng’s markets.
Food: Pad Thai (40-80 THB), grilled seafood skewers, mango sticky rice, Thai pancakes (rotee), coconut ice cream, fresh fruit shakes. Most dishes 50-150 THB.
Shopping: Handmade jewelry, clothing, coconut oil products, Thai silk, local crafts. Quality is noticeably better than generic tourist markets.
Lamai Night Plaza
Open Wednesday, Thursday, and Sunday, 5-10 PM. A fixed venue with regular vendors — good for midweek market cravings.
Tips: Bring cash (most vendors don’t accept cards). Bargaining is expected at craft stalls but not food stalls.
