Nusa Penida

The largest and most dramatic of the Nusa islands, Nusa Penida is a rugged paradise of towering limestone cliffs, hidden beaches, and crystal-clear waters teeming with manta rays and vibrant coral reefs. The island is much bigger than nearby Lembongan — about 10 times the size — so renting a motorbike (~$5/day) is essential as some destinations require an hour's drive. The most spectacular site is Kelingking Beach (named after the Indonesian word for 'pinky finger'), also known as T-Rex Rock for the cliff's dinosaur shape. Arrive early morning to avoid the crowds; the hike down to the beach is steep and dangerous but the views are incredible. Other must-sees include Broken Beach (a natural circle of rock with a sea tunnel), Angel's Billabong (a natural infinity pool only safe at low tide), Crystal Bay (the base for manta ray snorkeling trips — an experience of a lifetime), Diamond Beach on the far eastern tip (about an hour's motorcycle ride, with cliff views rivaling Australia's Great Ocean Road), Atuh Beach (a secluded cove with dramatic rock formations and a natural bridge), and Gamat Bay (excellent for snorkeling with vibrant coral). Despite its growing popularity, much of the island remains wild and undeveloped. Day trips from Bali are popular, but staying overnight gives you time to see both the western and eastern highlights.
