For a full day we would like to guide you along the underground San Jeronimo River in the amazing Grutas de Cacahuampilpa National Park in Mexico.

Located in the Mexican state of Guerrero, the Grutas de Cacahuampilpa National Park, and the cave system within it, is absolutely breathtaking.

After arriving at the Grutas, we will walk to the entrance of the San Jeronimo River. Once we get there, we will get into the river and swim toward the mouth of the cave. Once we’ve entered the cave, you will be exposed to a gigantic and stunning world full of incredible rock formations that have been forming for many, many years!

We will continue venturing along the river, deeper into the cave, and into the darkness, where you will get to connect with the underground in a way you’ve never thought possible. And, when the adventure is over, we’ll return to the light, where you can enjoy a great meal at the Cacahuampilpa Market.

While not very difficult, it is important that participants on this trip know how to swim. You should also be in good physical condition. However, this trip is open to people as young as twelve years old. Hence making it a great family expedition.

To join on this unforgettable journey along the San Jeronimo River in the Grutas de Cacahuampilpa, please send a request.

We also offer an easier caving adventure in the Grutas that will take you along the Chontacoatlan River.
