Grutas de Tolantongo is a thermal canyon park in the state of Hidalgo, built around a hot river that runs the length of a deep gorge. Turquoise water flows through terraces of mineral rock, a warm tunnel leads to a cave with a waterfall, and cliff-edge pools overlook the canyon. It is one of the most popular weekend escapes from Mexico City, and the one that surprises first-time visitors most.
What you will find
- The grottos: a cave with a warm waterfall pouring through the roof, and a lit tunnel you walk through chest-deep in warm water.
- The thermal river: a milky-blue river with natural pools where you can soak at varying temperatures.
- The cliff-edge pools: pools carved into the rock walls, with views down the canyon, which are the most photographed part of the park.
- A suspension bridge and trails: short walks along the gorge.
- A zip line: an extra cost and sold separately.
Water temperature is generally warm to hot, so expect to wear a swimsuit and water shoes for most of the day.

How to get there from Mexico City
By bus. Buses leave from the Terminal Norte to Ixmiquilpan, taking about 3 to 3.5 hours. From Ixmiquilpan, take a combi or taxi to the park, roughly 1.5 hours on a winding road. Plan the return journey before you go, since last services leave in the late afternoon.
By car. Take the Mexico-Pachuca highway north, then continue toward Ixmiquilpan. Allow 4 to 5 hours, and remember the last section of mountain road is steep and narrow. Avoid driving it after dark. Parking is available at the entrance.
By tour. Browse Tolantongo tours on GetYourGuide for options from Mexico City, which handle transport, usually with a very early departure.

Where to stay
Most people stay on site. The park offers cabins and camping areas along the canyon, and there are rooms in Ixmiquilpan for a cheaper base. Book in advance for weekends and holidays, and check which facilities each option provides. Staying overnight lets you enter the thermal areas early in the morning, when crowds are thinnest.
Best time to go
Visit on a weekday if you can. Weekends, Semana Santa and the Christmas holidays pack the pools. Early morning and late afternoon give you the best light and the smallest crowds. In the rainy season, the park can restrict river access, so check beforehand.
What to bring
- Swimsuit, towel and water shoes (rocks are slippery)
- A change of clothes and a waterproof bag for your phone
- Cash in small bills
- Sun protection and a light jacket for the evening
- Motion sickness tablets for the mountain road
Food is sold at stalls and small restaurants inside the park, with simple Mexican dishes at moderate prices.
Safety and etiquette
Do not swim in the river after heavy rain, as flow can rise quickly. Follow staff instructions, particularly on the hanging walkways and in the tunnel. Alcohol is sold in the park, so keep an eye on children near the cliff-edge pools. Do not take soap or shampoo into the water, since this is a protected river system.
Is it worth it?
Yes, if you are comfortable with a long journey. The combination of turquoise thermal water, a canyon setting and a warm tunnel is hard to match elsewhere in central Mexico. A one-night stay is the best way to see it without rushing. For regional information and events, the official Visit Mexico site is a useful starting point.
