Poços de Caldas, in Minas Gerais, is the perfect destination for a quiet weekend in the countryside. Located 260 kilometers from São Paulo—about a 3.5-hour drive—the city offers scenic overlooks, waterfalls, and even relaxing baths. In other words: there’s plenty to do in Poços de Caldas for those looking to disconnect from their routine without traveling too far.
Another notable feature of Poços (as the locals like to call it) is the fact that it is the only city in Brazil located inside an extinct volcano. That’s right! This unique geographical feature gives the town an air of mystery and a mineral wealth that has attracted tourists since the 19th century, when naturalists discovered the region’s therapeutic potential.
How about taking a stroll through an extinct volcano?
About 80 million years ago, the region south of Minas Gerais was occupied by a massive volcano that collapsed. As magma erupted, the center of the elevation caved in, forming a caldera approximately 35 kilometers in diameter.
Currently, Poços de Caldas occupies the inner rim of this depression. The mountains surrounding the city (such as the Serra de São Domingos) are, therefore, the rims of the volcanic caldera! When looking at satellite images of the region, you can clearly see the outline of the ancient volcano.
Volcanic past transforms Poços de Caldas into a healing destination
The lava may have stopped flowing, but the ancient volcano still leaves its mark on Poços de Caldas. The region’s soil contains mineral-rich rocks that enrich its waters, making them sulfurous and medicinal. The city has thus been a leading destination for health treatments since the Imperial period.
The hot springs gush from the ground at temperatures ranging from 38°C to 45°C. That’s why the city is perfect for enjoying relaxing baths and spa services.
