Tren Ecológico de la Selva: Iguazú National Park

The Tren Ecológico de la Selva is a narrow-gauge railway inside Iguazú National Park, carrying visitors from the Central station through subtropical forest to Cataratas and on to Garganta del Diablo, the station for the walkway to the Devil's Throat. The line was built by Alan Keef of Ross-on-Wye and opened in 2001, and trains depart about every thirty minutes during park opening hours. The operator is converting the fleet from propane to battery-electric traction.

Why this route

A line built to cross the country it shows you.

This is a railway designed around a protected forest rather than through one: low speed, wildlife crossings and a traction change specifically intended to cut noise and emissions inside the park. It is also the only way to reach the Garganta del Diablo walkway without a long walk, so it is part of the visit rather than an optional extra. Travel is covered by park admission, and the leg from Cataratas to Garganta del Diablo takes around twenty minutes.
