Caverna São Mateus — Terra Ronca

Verified

One of the richest caves in Brazil for speleothems, inside the Parque Estadual de Terra Ronca, with over 20 km of passages and the Rio São Mateus running through it. The original entrance collapsed millennia ago, so you enter through a narrow, steep fissure, descending about 5 m on a rope. Inside, monumental chambers open up — such as the Salão dos Travertinos Gigantes, the Salão das Agulhas, and the Salão das Pérolas — lined with white stalactites, calcite flowers, and multicolored travertine pools.

Entry

Before you go

A guide accredited by the Parque Estadual de Terra Ronca is required under SEMAD-GO rules; the group must stay together. Experienced regional guides (e.g. Ramiro, a specialist for over 30 years) lead the route and the photography. Typical day rate around R$ 100–200 per cave, varying with group size.
Dry season only, April to October. In the rainy season the river rises and there's a flash-flood risk inside the cave — no visits. Park hours: 8am to 5pm.

This isn't a walking trail but a caving expedition: a rope descent through the fissure (a "body-squeeze," one person at a time), crossings with water at waist/neck height, and a small underground waterfall and canyon. Visitors report more than 8 hours inside the cave. It takes good fitness plus a helmet, headlamp, and closed non-slip footwear.
