Gili T is ringed by the sort of powdery white sand people expect to find on Bali, but don't. It can be crowded along the bar-lined main part of the strip, but walk just a bit north or south and west and you'll find some of Gili T's nicest swimming and snorkelling beaches. You can discover more solitude in parts of the west and north coasts, where it will be you and your towel on the sand – although water and Bintang vendors are never far away.
Note that at low tide large portions of the west and north coasts have rocks and coral near the surface, which makes trying to get off the shore deeply unpleasant.
Many people simply enjoy the sensational views of Lombok and Gunung Rinjani (from the east coast) as well as Bali and Gunung Agung (west).
