If you’re considering a day of exploring some of Mexico’s hidden underground treasures, this San Sebastián de las Grutas tour might catch your eye. It’s an experience designed for those who love nature’s surprises—think limestone caves, underground rivers, and a refreshing cenote—all packed into an 11-hour outing. While I haven’t done the tour myself, I’ve gathered plenty of insights from travelers who have, and I think it’s worth sharing what you can really expect.
Two things I really appreciate about this experience are its focused, small-group setting, which means you’ll get plenty of personal attention, and its stunning geological features that make it more than just a walk-through. However, a possible downside is that access fees for the caves and cenote aren’t included in the ticket price, so you’ll want to budget that in. This tour will suit anyone eager for a natural adventure, especially if you’re okay with some walking and a bit of physical activity.
