Rainforest Adventures opened its Jacó gondola line in 2003, suspending open-air tram cars 80 metres above the Pacific coastal forest between Playa Herradura and Carara National Park. The 18-cabin system climbs 1.
2 kilometres through three distinct canopy zones — emergent crown, mid-story, and understory transition — designed by Swiss engineer Daniel Oertli, whose cable tensioning protocols allowed gondolas to pause mid-ride without hydraulic anchors. Each six-passenger cabin ascends at 1.5 metres per second, slow enough that motion-triggered flight response in resident sloths and toucans remains minimal.
The Central Pacific corridor shelters 11 primate troops, including white-faced capuchins that forage within two metres of the tram route during morning hours. Naturalist guides stationed in each gondola carry field radios synchronized to a spotter network on the forest floor, coordinating real-time wildlife sightings across the ascent. The upper platform sits beneath a 400-year-old Ceiba pentandra crown; its buttress roots anchor seven epiphyte species visible from the viewing deck. Rainfall here averages 3,800 millimetres annually, concentrated between May and November, sustaining the dense bromeliad clusters that mark the transitional rainforest biome unique to Costa Rica's Pacific slope.
Aerial tram tour Jaco operations integrate with four ground-level trail systems and a butterfly observatory constructed in 2011. The site functions as a transitional habitat study zone for researchers from the Organization for Tropical Studies, tracking canopy migration patterns in scarlet macaws displaced from logging zones 40 kilometres south. Guided tram rides include bilingual ecological briefings recorded by University of Costa Rica biologists, updated seasonally to reflect nesting cycles and fruiting patterns in Ficus and Terminalia species. The system transports 320 visitors daily during peak season, operating independently of ground weather due to enclosed cabin design and all-terrain cable anchoring tested to withstand sustained winds up to 90 kilometres per hour.
Rainforest Adventures Jacó remains one of three operational aerial trams along Costa Rica's 1,290-kilometre Pacific coastline. The route crosses two micro-watersheds feeding into the Tárcoles River basin, visible as rust-coloured currents from the summit platform during the dry months of January through April. The forest canopy here regenerates at 2.1 centimetres of growth per year, measured through dendrometer stations installed in 2009 along the tram's eastern ascent corridor.
