While most visitors crowd the main walkways and circuits, the Macuco Trail offers something completely different: a deep immersion in the Misiones rainforest with no crowds, no metal walkways and none of the roar of the main falls. It is wild Iguazu, silent Iguazu, where the only sounds are birdsong, insects and the crunch of leaves underfoot.
The 3.5 km trail takes you through the heart of the National Park to Salto Arrechea, a hidden 20-metre waterfall that drops into a pool of crystal-clear water surrounded by lush vegetation. It is Iguazu's best-kept secret and the perfect reward for those who enjoy trekking and nature in its purest form.

The Route
The Macuco Trail begins near the Central Station, where a sign marks the start. Unlike the main circuits, this is a natural dirt trail with roots, rocks and muddy patches after rain. There are no metal walkways or railings: you are in the real jungle.
The first 3 km are relatively flat, advancing under the jungle canopy. Along the path you can see enormous tree ferns, pindo palms, lapachos, Misiones cedars and countless orchids and bromeliads. The trail is marked with numbered posts indicating points of botanical interest.
In the final stretch, the trail descends steeply about 50 metres to river level. There are natural stone steps and roots that require care, especially if the path is wet. And then, at the bottom, Salto Arrechea appears: an elegant 20-metre waterfall dropping into a crystal-clear pool surrounded by virgin jungle. The solitude and beauty of the spot are absolute.
Wildlife on the Trail
The Macuco Trail is arguably the best place in the park for wildlife watching, precisely because there are few people. During the walk you are very likely to see:
- Capuchin monkeys: moving in groups through the treetops
- Toucans: the toco toucan and aracaris are frequent here
- Coatis: less habituated to humans than those on the main circuits
- Blue morpho butterflies: enormous butterflies with iridescent metallic blue wings
- Tegu lizards: large, harmless lizards basking in the sun
- Woodpeckers: several species drumming on tree trunks
Trekking tip: Wear closed-toe shoes with good tread (not flip-flops), bring at least 1 litre of water per person, DEET insect repellent, and if you want to swim, swimwear and a towel. Start early (8:00-9:00) to have the trail almost to yourself. And bring binoculars if you are a birdwatcher.
