The tractor hums and coughs as it noses up a narrow access road; mist from the valley clings to your helmet and the Pacific glints far below. You step out at the first platform and the forest leans in, leaves whispering like a crowd waiting for a stunt. Twelve platforms, ten cables and one famously long line cut across a slope that’s less about dizzying altitude than about immersion: you fly through a transitional Costa Rican rainforest that keeps one foot in the dry Pacific foothills and the other in humid interior growth. The string of platforms moves quickly—each launch is brief, focused, and taut with the air beneath you.
