Snorkeling Day Trips to Nusa Penida are popular from Nusa Lembongan. The popular places are Manta Bay, Crystal Bay, and the underwater Buddha statues. It is generally a short boat ride of 20-30 minutes and you can spot Manta Rays, the Mola-Mola sunfish, and dolphins. Many snorkeling schools are available on the island, and you can book a trip on the spot or in advance.
