Lamai Beach Samui: Travel Guide, Hin Ta Hin Yai & Stays (2026)
Direct Answer: Lamai Beach is Koh Samui’s second-largest resort beach, stretching 4 kilometers along a crescent bay on the southeast coast. Famous for the legendary Hin Ta and Hin Yai (Grandfather & Grandmother) granite rock formations, Lamai delivers a relaxed blend of deep-water swimming, authentic night markets, cliffside viewpoints, and tranquil beachfront resorts with less congestion than Chaweng.
Coastal Geography & Scenery of Lamai
Stretching four kilometers along the southeastern shoreline of Koh Samui, Lamai Beach provides a more laid-back, community-centric atmosphere than neighboring Chaweng. Ringed by lush granite hills and swaying coconut groves, Lamai is renowned for its striking geological features, most notably the famous Hin Ta and Hin Yai (Grandfather and Grandmother rocks) situated at the southern promontory.
The bay forms a broad, gentle arc. The northern section features shallow, calm waters ideal for families with young children, while the central stretch boasts deep azure water with an immediate gradient that makes it one of the premier swimming bays on the island.
Swimming Conditions, Seabed & Waves
Lamai’s central beach is characterized by deep water within just a few meters of the shore. The sand is rich, golden, and slightly coarse, which keeps the sea clear under normal conditions. Swimmers can enjoy true open-water swimming without navigating shallow reef flats.
Safety & Tides: During the calm season (January through September), Lamai offers glassy, warm water. However, because it faces southeast toward the open Gulf, winter monsoon swells (November to mid-December) can create strong shore break and undertows. Red safety flags are displayed when conditions are hazardous. Additionally, several resorts maintain netted swimming enclosures during jellyfish awareness seasons.
Lamai Sunday Walking Street & Local Culture
Every Sunday evening, Lamai hosts one of the island’s most vibrant cultural gatherings: the Lamai Sunday Walking Street Market, operating from 4:30 PM to 10:30 PM along the main street and bridge leading to the beach.
This market offers an authentic taste of southern Thai culinary culture: crispy fried chicken with sticky rice, freshly made coconut pancakes (Kanom Krok), spicy southern curries, grilled seafood skewers, and handmade crafts from local artisans. Beyond the market, Lamai’s southern end features scenic cliffside cafes such as The Jungle Club, offering panoramic bird’s-eye views across the entire bay.
