Borneo Canopy Walk, Borneo | Are you interested in seeing what a 130-year-old rainforest looks like up close? Venture to the Danum Valley Conservation Area in Malaysia where the Borneo Rainforest Canopy Walkway offers visitors an unmatchable experience in the oldest rainforest on earth. The walk is nearly a thousand feet long and suspends between ancient trees roughly 90 feet in the air. And don’t worry – the walkways are “tree-friendly,” meaning no damaging wires are strung through the trunks.
