About La Gruta Hot Springs
A series of geothermal pools 10 km outside town, with a famous tunnel leading to a domed cave pool fed by warm mineral water. As one of the headline attractions in San Miguel de Allende, La Gruta Hot Springs is the kind of stop most first-time visitors build a half-day around — and that returning travelers keep finding new angles on. Thermal pools and a tunnel-cave grotto.

La Gruta Hot Springs fits squarely into that story, which is why it lands on almost every shortlist of things to do in San Miguel de Allende, Mexico.
