Ao Nang ( map ) is a laid back beach town where you can see beautiful islands on the beaches as well as karst cliffs. There are lots of shops, but it doesn't feel overly touristy here.
Tiger Cave Temple ( map ) is mountain-top temple surrounded by jungles. Climb 1237 steps to reach the top — the view will be worth it! You'll see lots of cute monkeys on the way.
