There is beach, nice nature and it is close to Khao Lak National Park (nice) and Khao Sok National Park (excellent).
It is one outstreched beach.
Low season is really bad, with nearly everything closed and lots of rubbish on the beach coming from the sea. Also the waves will splash onto the beach, very often no swimming possible.
Enough places to eat and drink, but this a nice example of the hotels trying to keep everybody in the hotels.
