[World's 15 most spectacular swimming pools]1. Alila Uluwatu, Bali, Indonesia

 

 

This spectacular cliff-top infinity pool appears to float in space. The scary-looking cage at the end is actually a user-friendly cabana designed for gazing out over the horizon in comfort.

Wonder why the water is empty? Lovely as this 50-meter beauty is, guests are probably using one of the private pools that come with each of the 84 villas.
