Billabong is the stuff Instagram dreams are made of. It’s basically a little lagoon, set in the middle of the black and craggy volcanic rock. It’s located on a cliff right down the path from Broken Beach (see above). Nusa Penida’s massive waves crash into the cliff and splash water into the lagoon. It is possible to swim in the lagoon (something that’s super popular with the selfie crowd) but be warned that people have been swept out to sea by the powerful waves.
Traveler’s tips: Billabong is literally right down the pathway from Broken Beach, maybe a two-minute walk.
