Grutas Tolantongo - Hot Springs in Mexico

Mexico is a resource-rich nation in terms of hot springs, due to its location on the Ring of Fire.

I visited an amazing spot where seems to symbolize the resources.

Gallons of hot spring water gushed from giant caves, and there was a theme park centering the geothermally heated river.

Sacred Waterfall

It is 3.5 hours’ drive from Mexico City.


You will see a sacred waterfall deep in the mountain.


A hot spring is gushing from the calcareous rocky hill, and behind the waterfall, there are two caves.


The water flowing out from here makes a warm river, and an extensive theme park centering hot springs is surrounding it.


Hotels (reservation unavailable), camping grounds, and restaurants are available in the park.

Calcareous Caves

Small Cave1

In the left side of the waterfall, you will find a smaller cave around 50 feet length where you can get inside.

Small Cave2

Hot water is gushing everywhere in the complete dark, and you will have zero visibility.


It seems apparently dangerous due to some ponds in the dark.

Large Cave1

Behind the waterfall basin, a larger cave has a great pool in a state of nature.


The water temperature is not so hot (around 100 degrees F), but it is rather comfortable in warm air in the cave.

Large Cave3

The water looks milky white and has smooth texture.

Large Cave2

From the ceiling of the cave, gallons of water are provided into the pool.

It this kinda ascetic trainings?
Maybe, maybe not.

Milky-white River1

Under the column of water, Mexican people enjoy the fresh spring, although it looks like a kind of ascetic training.

Geothermally Heated River


The water makes a hot spring river streaming in the theme park.


Here, you will find restaurants, and the water temperature is around 86 degrees F.

Milky-white River2

The time to visit needs to be noted.

Milky-white River3

It is better to avoid the rainy season (June through September), because the river may get dirty after rain.

Scenic Outdoor Baths

Paraíso Escondido1

There are also open-air baths with a superb view, near a hotel (Paraíso Escondido) on the mountainside.


The rich resource of hot springs meets Mexican culture that they do not take it too seriously about safety and nature conservation in a positive and negative way; which realizes the amazing theme park.
