Uluwatu is a Surfers Heaven. It attracts surfers from all over the world for it's range of surfing beaches. But not only are the beaches in this area good for surfing, but they are beautiful. When People go to Bali they expect beautiful beaches...then they see Kuta Beach and get disappointed. Well, the beaches here won't disappoint, although not all are suitable for swimming.
There are many luxurious resorts perched atop of the cliffs which have stunning views. If you want to get a feel for these views, then go to Uluwatu temple, which is also perched on the edge of a cliff and a must see.
Accommodation and things to do are very spread apart, and for that reason it's a great place to relax and get away from the crowds.
