You'll follow your guide, discovering natural pools such as El Salto, where a swim is on the cards, and testing the limits of these machines. It'll all culminate in a nerve-testing drive over a 470m-long, 150m-high wooden suspension bridge above the River Cuale.Now, you'll be heading up into the treetops on a zipline course that'll make you scream with delight.
