Lost Worlds With Monty Halls and Leo HouldingTV Show

Monty and Leo are in Borneo, on a mission to reach a part of the jungle no human has ever visited. Their goal is to be the first to climb a massive 300 metre cliff deep in the Melinau Gorge, and survey it for wildlife. It’ll be tough - even today, vast tracts of Borneo’s impenetrable rainforest remain unexplored. With just seven days of supplies, will they reach the top in time?
