After a couple of days in Bali, we took a detour to the neighboring island Nusa Penida. Just a short ferry ride from Bali takes you to another world that lacks the tourism infrastructure of Bali. Penida Island is a famous scuba diving destination known for its Mola Mola (big weird creatures also called sunfish), manta rays, and strong and sometimes dangerous ocean currents. We stayed and dove with a small Czech dive resort, Penida Dive Resort.  Above the water we rented scooters and traversed the entire island and found secluded beaches, friendly locals who didn't understand a word of English, a Hindu ceremony in a temple within a giant bat cave, a hollow sea crater in a cliff, and a clear blue swimming hole below a waterfall.
