Sumbawa is a little visited island in eastern Indonesia which has long attracted surfers with its world-class surf conditions. But it's not just the waves that draw them; it's the whole package. With its exquisite beaches, clear warm waters, jungle-clad interior, quiet villages and friendly locals, the island epitomises an idyllic tropical paradise. It remains far less developed than its neighbours of Bali and Lombok, which makes it an ideal destination for travellers seeking an off-the-beaten-track adventure. The island features a number of fascinating archaeological sites and offers a range of exhilarating activities, including hiking to the top of the volcanic Mount Tambora, swimming and snorkelling in the island's calm tropical fish-filled waters, or trekking through the lush forest to discover some breathtaking waterfalls.
