In the morning, before dawn we will leave from
Querétaro bound for the Tolantongo Caves, one of the
most surprising natural paradises in the state of Hidalgo.
This oasis surrounded by mountains features an impressive waterfall with a grotto and cave at its base. These formations feed a turquoise thermal river, whose colour comes from lime and magnesium particles released by the rocks. The river flows for a long distance and contains various natural pools where you can swim.
The place has another section called “Las Pocitas” which are
artificial and shallow formations; to reach
you will have to take the transport or walk along the path for about 25
minutes, in this area you will also find a pool with
slide, a suspension bridge, another grotto with water, and zip line
with extra cost.
Within the facilities you will find restaurants, bathrooms,
showers, camping area, grills, hotels, stores, rental
of tent houses, mats, aquatic clothing, blankets,
firewood, practically everything, so that the fun never ends.

Important note: in the rainy season due to weather reasons, the river can completely change from blue to brown due to the currents that come down from the mountains
