The Rio Secreto Tour was a high priority on our to-do-list while staying in Playa del Carmen. That’s why we booked the Rio Secreto Plus tour way in advance. I am so glad, that we took this unique underground river tour, during which we were able to observe natural history dating back millions of years, hike and swim through a route of about 1 km full of beautiful stalactites and stalagmites. This tour was an amazing experience combining adventure and nature.
