Ao Suan Yai
Ao Suan Yai stretches along Ko Mak's windward side, where afternoon breezes bend the palms and the water stays shallow enough to wade fifty meters out. A handful of bungalow clusters share the sand with coconut plantations that run to the tideline.

Questions people actually ask about Ao Suan Yai.
Is Ao Suan Yai safe for swimming throughout the day?
Ao Suan Yai is generally safe for swimming during the dry season (November-April) with calm, clear waters and a gentle sandy slope. The west-facing beach experiences minimal currents and waves in good weather. No lifeguards are stationed, as Ko Mak maintains a laid-back, undeveloped atmosphere, so swimmers should exercise personal caution. During monsoon season (May-October), waves can become rougher and water cloudier, making swimming less advisable. The beach is shallow near shore, suitable for wading and relaxed swimming. Check with your resort about current conditions, and avoid swimming during storms or rough weather.
When is the best time to visit Ao Suan Yai for sunsets?
Ao Suan Yai is Ko Mak's premier sunset beach, facing west with stunning views toward nearby Ko Kham island. The best sunset viewing period is November through April when clear skies are most common and the sun sets directly over the water. December through February offers the most reliable weather for spectacular sunsets. Arrive 30-60 minutes before sunset to secure a good spot and watch the changing light. The dry season provides vibrant orange and pink skies, with silhouettes of islands creating dramatic scenes. Sunsets can be beautiful year-round, but monsoon clouds (May-October) may obscure views.
