Nusa Lembongan is a sleepy island southeast of Bali that can be reached with the fastboat in approx. 45 minutes. All in all here it is a bit more expensive than in Bali but for that you get an impression of the fascinating originality of the country and the indonesian people.
Famous for its beautiful coral reefs and rare manta rays a snorkeling trip is inevitable. Ebb and flow are very strong on this island, therefore it is worth spending some more money for an accomodation with swimming pool.
If you rent a scooter you can discover the secret attractions of the island.
