About this place

Volkansaun Lama Malelat

Hidden deep in Oecusse’s southern interior near the Indonesian border, the Malelat mud volcanoes present an eerie, otherworldly lunar landscape. Several active mud cones bubble and belch thick, mineral-laden gray sludge, accompanied by a faint sulfuric murmur. Surrounded by steep forested hills, the site is an extraordinary geotourism curiosity.
