How to Get to Las Grutas de Tolantongo

By Car

We chose to go by car and we were so happy we did! I loved the flexibility it gave us and we didn’t need to worry about bus routes or schedules. We were on our own time!

Car directions will vary depending on where you come from. I’d recommend using Google Maps to plot your best route!

By Shuttle

It’s a long drive, but you can bus if you want the cheapest route. If you’re coming from Mexico City, head to the North Bus Station and hop on the Ovnibus or Flecha Roja line from Platform 7 or 8 towards Ixmiquilpan Hidalgo City. Once you arrive, find the Microbuses Station in the San Antonio parking where you’ll be able to hop on a bus to Grutas Tolantongo. (Shuttle Service Schedules)

Waterfall at Las Grutas Tolantongo

Las Grutas de Tolantongo

There’s SO much to see at Las Grutas Tolantongo, so give yourself at least an entire day to enjoy all its magic. At least. I honestly felt like one day wasn’t enough! I fully plan on heading back down there at some point to camp!

With towering cliffs that reach up to 492 feet, Las Grutas Tolantongo is the perfect destination for thrill-seekers looking for adventure. The region is also home to a variety of flora and fauna, including cacti, agave, and various species of birds, reptiles, and mammals, providing nature lovers with plenty of opportunities to explore and observe the local wildlife.

Las Grutas Tolantongo

For those who are more adventurous, Las Grutas Tolantongo also offers a range of activities that are sure to get your adrenaline pumping. Visitors can hike through the stunning canyon, rappel down the cliffs, or go zip-lining, giving them an opportunity to see the natural beauty of the region up close and personal. There are also guided tours available that take visitors to the area's hidden caves, where they can explore the geological formations that have been carved out over time.

Its activities can be roughly divided into three categories: the hot springs pools, the river, and the caves. Let’s dive in, shall we! *shameless pun. Not sorry.

The Hot Spring Pools

Once at the gated entrance, hang right for the holy grail of hot springs. The warm waters, which are enriched with minerals, flow through a series of cascading pools that are set into the cliffs. It’s becoming Instagram famous for good reason!

We went on a Saturday and while it was busy, we still managed to get multiple pools to ourself! There are TONS to choose from, and each one is totally unique. The hottest pools are at the top of the hill and get progressively colder as you make your way down the mountainsidee. Why? Each pool cascades into the next.

Is Grutas Tolantongo Natural?

Yes, for the most part! The water is all natural and free flowing, but the pools are manmade. I’ll be honest, I’m usually not one who goes for the manmade hot spring structures, but they did these so well! They’re covered in calcium, which gives the pools their yellow-white walls and make them feel a little more natural than other manmade hot spring resorts. They have waterfalls, little caves, and other features that make you want to visit each and every one, which honestly feels like an impossible feat.

The Hotel Paraiso Escondido, a few restaurants, and a zipline is located in the part of the park as well!

The Hot Spring River

At the entrance gate, hang left to continue down the winding road that leads to the second half of the park. This is where you’ll access the hot spring river and caves, which we’ll dive into next!

The river is partitioned into sections to create pools deep enough to swim in and is this unreal shade of blue. Like someone took a bottle of blue gatorade and dumped an entire ocean’s worth into this ravine–don’t drink it, though. But DO grab a handful of mud from the riverbed and give yourself a nice exfoliating facial while you’re swimming around!

Hungry? This area has a few more restaurants to choose from and plenty of space to spread out and soak up some rays. It’s also where the overnighters set up camp.

Thermal Cave at Las Grutas Tolantongo

Tolantongo cave and tunnel

Walk up river for maybe a half mile to find the epic Tolantongo Cave and Tunnel. I’d recommend renting a locker to store your belongings for this part! You’re gonna get wet. Like super wet. Trust me.

At the end of the pathway, you’ll see an insanely gorgeous waterfall that may just be the most beautiful waterfall I’ve ever seen in my life. No joke. And at the base? The entrance to a massive cave.

The waters that flow from this cave and tunnel feed out to the entire site and travel all the way to the end of the Tolantongo canyon. That’s a hell of a lot of water, which also means the current is pretty dang strong.

Pro tip: Only enter the cave if you’re a strong swimmer. It’s deep and the current can sweep you off your feet.

The tunnel, which is carved into the mountainside, is almost 500 meters long and provides visitors with a stunning view of the canyon as they make their way to the pools. The tunnel's walls are adorned with colorful murals that depict the history and culture of the region, making the journey to the hot springs an immersive experience.

Waterfall at Las Grutas Tolantongo

The main chamber has a massive hole in the roof where gallons upon gallons of hot water aggressively rushes out per minute. It honestly made me a little nervous. All of a sudden, I was way too aware of the fact that I was standing under a ton of heavy water forcing its way through a hole in the ceiling. So what did I do? I went in further. I know, I know. Proceed at your own caution.

Waterfall at Las Grutas Tolantongo

In the back, right-hand side of the cave, you’ll see a small, dark opening. If you brought a waterproof headlamp, now’s the time to break that baby out. Head over to the cave wall and pull yourself along it–the current is too strong to swim. Once you get close, you’ll be able to feel a rope fastened to the wall under the water. Use that to help pull you through the opening and into the second chamber. At the far end you’ll find another hot waterfall–stand under it for a little massage, and when you’re ready, let the current float you out the opening and back into the main chamber. It’s super fun.

Restaurants in Las Grutas Tolantongo

Las Grutas Tolantongo

There are plenty of restaurants to choose from, all offering local cuisine, including barbacoa, tacos, and tamales, which are made using traditional cooking methods and locally-sourced ingredients. The region is also famous for its pulque, a fermented beverage made from the agave plant, which has been a staple of Mexican culture for centuries.

Restaurante Paraíso Escondido

You’ll be able to find a variety of Mexican dishes at the hotel restaurant and bar. It’s also located right next to the hot spring pools!

Pollo Rostizados

On the other side of the park by the thermal river and caves, you’ll find this little chicken joint. I didn’t try it myself but love me a some tasty chicken!

Restuarante Melacón

We went here for the indoor seating and the thermal river view–top-notch people watching.

Restaurante Las Palomas

A little closer to the caves, Google says this is a pizza spot, but it also offers Mexican food? Not sure, but the location was awesome. Give it a try and let me know how it goes!
