Sumbawa is located east of Lombok, and is larger than Bali and Lombok together. It has a  population of about 800.000. The majority of the island is occupied with agriculture and fishing.

Several large mountain chains cross the island, the northernmost of these is volcanic. The highest mountain here, the Tambora volcano, had in the year 1815 the until now largest volcanic eruption known in modern history. Dust particles in the atmosphere caused a global cooling, and the year 1816 was called "the year with no summer", where the crops in Europe and north America were reduced to a fraction. Today you can climb to the top of this mountain, and the view is supposedly very impressing. The truly awesome crater is one of the most spectacular sights in Indonesia. The two largest cities are Sumbawa Besar in the west and Bima in the east. Both cities contain an old sultan palace and also facilities for visitors. The mass tourism has not reached Sumbawa yet, but the island has a lot of lovely scenery and culture to offer and is absolutely worth a visit.
