Las Grutas Tolantongo, also known as Las Grutas de Tolantongo or Las Grutas Hot Springs, is one of Mexico’s most impressive natural attractions. The stunning Tolantongo Canyon is home to a series of hot springs and breathtakingly beautiful geothermal pools. It’s open to the public and one of the prettiest spots in this part of Mexico.
Las Grutas Tolantongo has nine thermal pools that range in temperature from a cool 98 degrees Fahrenheit to nearly 111 degrees Fahrenheit; don’t stay in the latter for too long (and be sure to drink tons of water).
