It is in Ao Nang that the beach is not very comfortable (it is very shallow to the right of the pier, you can endlessly walk ankle-deep into the sea, and on the left it is a little more interesting, but the water is muddy and a lot of huge jellyfish) you can go further along the Monkey Trail to the neighboring beach where the water is more pleasant, but if you were at Rally Beach or on the islands, then rather You'll probably want to go back there.
