Rawhiti Cave

Rawhiti Cave, also known as Manson Cave, is a single large limestone cave in the hillside of the Dry Creek Valley 7 kilometres southeast of Tākaka on the South Island of New Zealand. It is referred to as Manson Cave in the NZ Topo Map, after owners in the early 20th century, however the cave is known as Rawhiti Cave locally, and on DoC information panels and in brochures.The cave's entrance is one of the largest cave entrances in New Zealand with an opening of about 40 metres wide and up to 20 metres tall. The ceiling is densely covered in stalactites which become increasingly finer deeper down into the cave. A short walking track leads halfway down into the cavernous opening to a viewing platform.
