The waters of Sanur are protected by a long string of offshore reefs, creating large, warm shallow, safe lagoons that are perfectly clear and excellent for swimming, snorkeling and a whole array of water sports. Surfers will be pleased to know that the reefs around Sanur produce some of the best waves in the world in the right conditions although they can be very shallow at low tide. But there are more consistent waves beyond the reefs good for surfing.

Sanur is also the launching pad for visitors who want to dive and explore the splendors of the nearby island of Nusa Lembongan. Nusa Lembongan is approximately 8 square km in size, and is one of three neighbouring islands, the others being much the larger Nusa Penida and tiny Nusa Ceningan.

Many areas around the island are good for diving and snorkeling, with abundant marine life and healthy corals. Surfing can get a bit crowded, but the waves are good. There are several white sand beaches away from the main centers which are virtually never crowded.

As a place where tourism first flourished in, Sanur has some of Balis’ historic hotels. There are a lot of restaurants and cafes along the coastline. For budget meals you may want to try the Pasar Malam (Night Market) at the northern end of Jalan Danau Tamblingan where it meets Jalan Pungutan.

Sanur's splendid paved beachfront cycle-path stretches some 5 km from Jalan Mertasari area in south Sanur, north to the main beach at Jalan Hangtuah. This makes for a lovely scenic bike ride, especially in the early morning. The more active could try one or more of the many watersports on offer at Sanur Beach. Try kitesurfing, windsurfing, wakeboarding, surfing or paragliding.

For those less active, hire a banana boat and hit the calm waters. The surf here is not great by Bali standard but there are reasonable breaks about 1 km offshore during the northwest wind season (about October-March). In that period you will have no problem locating the breaks-just follow the locals. Boards can be rented on the beach for Rp 100,000.

For one of a kind experience, you should try the Sea Walker. A safe and exciting underwater adventure Sea Walker is a unique diving system, that provides an opportunity to observe the underwater world to a depth of 15 feet without certification, and without getting your hair wet. Participants actually walk along the bottom of the sea, rather than swim while numerous exotic fish and sea life are found all around.
