Bandar Seri Begawan is a city of two terrains: the stilted water villages that make up some of the city's historic aquatic districts stretch out into the sea, while drier districts spread out over the flatter areas of land. The beaches around the area offer vibrant undersea life, drawing scuba enthusiasts and snorkelers from around the world. Above ground the gold-domed Sultan Omar Ali Saifuddin Mosque dazzles with its intricate marble design and museums provide ample cultural stimulation.
