Lost Worlds With Monty Halls and Leo Houlding

Eighty percent of Guyana is covered by dense primary rainforest. It is one of the richest eco systems on the planet; the jungle teeming with wildlife. Monty and Leo’s goal is to get to the highest possible point in the remotest possible part of the jungle and study the wildlife there. That means finding the tallest tree they can and climbing high into the canopy to explore a world that few people ever see.

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.

Deep in the Borneo rainforest, Batu Lawi rises 250 metres above the canopy. This sandstone spire has much to interest both Leo and Monty - Leo plans to climb a new route up this challenging pinnacle. Aided by Leo, Monty plans to survey the wildlife living at the top middle and bottom. As usual the pair only has seven days to complete their mission.

Beneath Borneo’s rainforest lies one of the worlds largest cave networks. So far 300 km of passages have been discovered; with more being found on every expedition. Monty and Leo are on a journey to explore this subterranean Lost World.
