I LOVE Tawan beach Koh Lan Island is the first beach i went on the first day. it nice white sand small beach. the best time to get there should be low season around July-August it will be less peoples. for the bed rent 100THB the price for to rent the bed depend on season also for while day. foods is so expensive over there.
This beach did not disappoint. The sand was white, the water was warm, although the waves come in pretty high. You do have to pay for a longe chair to sit on the beach, but it's worth it. There are plenty restaurants and shops along the beach if you want to take a break from the sun and sand.
