Lombok has an extensive network of roads, but public buses and bemos are generally restricted to main routes. Bemos, or minibuses, run on routes all over the island, or you can charter your own. Away from these you have to hire a cidomo (pony cart), get a lift on a motorcycle or walk. In the north-east and south there is usually some public transport between the bigger towns, but it might be far between, and extremely sparse after dark.
You can get around the whole island and to most of the remote locations if you have your own transport. A motorcycle is the cheapest and most versatile option, though a rental car with good ground clearance will get you a long way. Mountain bikes are ideal, as you can put them on boats for coastal hops or island visits.
Outrigger boats, called prahu are used for short trips to snorkelling spots or surf breaks, while slighty larger boats (jukungs) travel between islands.
