Nusa Penida

Nusa Penida is Bali's high-energy dive hub. The Nusa Penida Marine Protected Area protects 20,057 hectares of reef shared by Penida, Lembongan, and Ceningan, home to reef mantas year-round and seasonal mola mola. Expect swift drifts, thermoclines that can drop water to 16°C, and world-class coral slopes. Most diving is from fast boats, with easier drifts along the north and more exposed sites on the south and in the Ceningan Channel. Snorkelers target manta encounters and calm bays, while topside days hit Kelingking, Diamond and Atuh beaches, and Goa Giri Putri temple. Access is via Denpasar's DPS airport and the Sanur fast-boat piers, making quick combinations with mainland Bali easy.
