Danau Ranau covers about a hundred and twenty-five square kilometres in a caldera on the boundary between South Sumatra and Lampung, which makes it the second largest lake in Sumatra after Toba, with the cone of Gunung Seminung standing on the southern shore. It sits at around five hundred metres and the surrounding country is coffee, pepper and paddy. Hot springs come up on the Seminung side and at Pulau Marisa, a small island in the lake, and the water is used for fishing - the mujair and other species are netted and served fried in the shore warungs. It is a domestic destination almost entirely, with cottages and simple guesthouses on the shore and very few foreign visitors, and the roads in from either side are long.
