Grutas Tolantongo
Hgo.
Grutas Tolantongo is a natural hot spring canyon resort in Hidalgo celebrated for its tiered, cliffside thermal infinity pools overlooking lush valley views. Visitors highlight the warm, turquoise mineral river, cascading waterfalls, and steaming grotto caves that double as natural saunas. The expansive park also features suspension bridges, ziplining, and on-site lodging and camping options.
Commenters are overwhelmingly captivated by the resort's breathtaking, bucket-list beauty and soothing thermal waters. However, practical concerns frequently arise regarding extremely slick and hazardous wet surfaces, the long and intimidating mountain drive, and variations in water color depending on the weather and season. Some past visitors also caution that certain pool areas can carry a noticeable chlorine smell.
- Arrive early around 8:00 AM on weekdays to avoid massive crowds
- Wear sturdy water shoes with strong grip to navigate very slippery stairs and caves
- Bring cash for on-site extras like canyon ziplining
- Expect water color to shift from turquoise depending on recent rainfall and sunlight
- Be prepared for a winding, steep drive down into the canyon
