Attraction Details : The highlight of KohPhayarm is Yai Bay (Large) which is to the South West. Living up to its name, Yai Bay has a large semi circular shoreline of over 4 kilometers. During low tides Yai Bay offers visitors with a beautiful white sand beach with fine sand that is soft to stroll on. The color of the sand is mixed between yellow and grey which forms an attractive layer-like effect at dawn.
