Tour description provided by Viator

Escape Bali for a day and spend it on the turquoise waters of Nusa Lembongan, a small, low, protected island about 7 miles (11 km) southeast of Bali, just across the Badung Strait. After arriving by comfortable, air-conditioned catamaran, you’ll anchor at a private pontoon where you can enjoy a variety of water activities, including a waterslide, banana boat rides and snorkeling. You can even take a small boat to the island for a tour, if you wish. This family-friendly tour includes snacks, a buffet lunch and hotel transport.

After hotel pickup by air-conditioned vehicle, your day on the water begins with a 1-hour catamaran cruise on the Bali Hai II from Bali to Nusa Lembongan (Lembongan Island), a small isle off Bali’s southeastern coast. During the cruise from the Benoa harbor, enjoy coffee, tea and pastries on board and watch a snorkeling demonstration, if you or a family member are a beginner.When you arrive at Lembongan Bay, the catamaran pulls up next to a large, purpose-built reef pontoon, your base for the day. All activities you choose to participate in take place on or depart from this pontoon. Locker use is included for your valuables.Included activities:See the bay’s exotic marine life and colorful coral from the comfort of a semi-submersible coral viewer, or try snorkeling for a closer look. Enjoy unlimited banana boat rides, a 115-foot (35-meter) waterslide and a diving board. Or, just relax in the sun and enjoy the beauty of the bay. If you don’t want to go in the water, you can still see what lies beneath via the pontoon’s underwater viewing chamber.The buffet lunch is open on the air-conditioned deck for about 2.5 hours; when it closes, coffee and tea continue to be available for another hour. Starting just before midday, the first of three 1-hour tours to the island depart from the pontoon — if you’re interested in wandering the narrow, colorful streets of Nusa Lembongan, just hop on the boat and go. Explore on foot, admiring the island’s white-sand beaches, cliffs, Balinese architecture and views of Mt Agung.When your time in the water comes to an end, rinse off if you wish with a fresh-water shower on the pontoon. Then, after a head count to make sure everyone is on board, make your back to Bali on the catamaran, listening to live music during the 1-hour cruise. Your tour ends with drop-off at your Bali hotel.Optional activities at your own expense:Scuba diving, massages, parasailing (single, tandem and trio flying is available) and the Aquanauts submerged marine walk are all available on the pontoon for an additional cost. Towel rental is also available if you don’t have or forget to bring your own. Purchase cocktails and other adult beverages from one of the two fully licensed bars.Sample buffet lunch menu:Pastries and muffinsColeslaw and salads (potato; mixed green; tomato and onion; pasta)Bread rollsFried noodles with vegetablesVegetable spring rollsSteamed riceGrilled meats (prawn satay; chicken legs; beef steak in BBQ sauce)Fish steaksGrilled sweet cornPork satayFresh fruitJajan pasarCheese and crackersShrimp crackers
