While divers are able to regularly swim with black tip, those who prefer to just drifts in the currents with a snorkel, fins and mask are never left disappointed by the more than 6,000 species of marine life living just off-shore.
The three Gili islands are still excellent for snorkeling despite the devastation wreaked by the El Nino weather phenomenon in 1998. Some 90% of the hard corals around the islands down to 20 meters suffered badly at the time from bleaching and are still recovering. While you can snorkel directly from the beach, a good deal is to join the daily snorkeling tour at the very reasonable rate of Rp35,000 per person. As the boat has a glass bottom, those unable to snorkel, such as young kids, can also have the opportunity to see a wide array of beautiful multicolored tropical fish and, if lucky, even the odd turtle. A tip here: bring your own snorkeling gear as the quality of the stuff available for hire leaves much to be desired.
If the weather is good (which it usually is) beautiful red sunsets can be seen, with the sun setting in the west over Mount Agung, Bali. Either head for Gili Trawangan’s northern coast else climb the island’s 100-meter hill (going up here is the only time you are likely to venture into the island’s interior during your stay).
As for Gili Air and Gilo Meno, they are even quieter than Gili Trawangan. Accommodations and restaurants are basic, but then that's part of the charm. If you need more facilities, it’s more convenient to stay on Gili Trawangan and make day trips to these two islands.
