Lost Worlds With Monty Halls and Leo Houlding

Waterfall (1x2)

Air date: Feb 20, 2015

In a remote corner of Guyana’s western highlands lie two huge waterfalls, Oshi and Kamarang. Both are thought to be 150m high, equivalent to the height of a fifty storey building or three times higher than Niagara Falls. Neither has been accurately measured and as far as we know, no one has ever surveyed the wildlife that lives there. Monty and Leo lead a seven day expedition to this lost world. They have two goals; search the area for wildlife and measure both waterfalls. Leo attempts to climb Oshi and they both descend Kamarang, measuring both waterfalls in the process.
