Brunei is one of the richest countries in the world, and known for its reserves of hydrocarbons. This state, formed by two enclaves to the north-west of the island of Borneo, is covered by equatorial forest over more than half its territory. The coasts are not very interesting; however the capital, Bandar Seri Begawan
, has one of the largest mosques in Asia
, and is worth visiting. Travel to Brunei if you are passing through, but it is not really worth the trip just for the sake of it.
