Nusa Lembongan is one of the most popular destinations for day cruises on the many pleasure boats sailing from Bali. Depending on whether you sail or motor, the trip can take anywhere from one hour to two and a half. The pristine white sandy beaches with colourful sea life, so diving and snorkeling are very popular sports. The less adventurous can enjoy glas bottomed boat rides. A number of reef breaks are popular with surfers, and the view back to Bali with a looming Mount Agung makes a fabulous backdrop.
