Angel's Billabong is a stunning natural infinity pool on the cliffs of Nusa Penida's southwest coast. Volcanic rock has formed a natural basin that fills with crystal-clear ocean water at low tide. The pool floor is covered with green and blue algae, creating an enchanting effect like a painting. During low tide, careful swimming is possible, but beware of sudden waves and slippery rocks. The site is located near Broken Beach and both can be visited together. This is one of the most unique natural formations in Bali and a must-visit for photographers.
