Rio secreto - Beautiful note, passionate guide (Benito). On the other hand they did not confirm the time of pick up at the hotel the day before... by email so wait an hour. Ban on taking phones and at arrival extremely expensive photos if he sold them cheaper they would surely sell much more it is a shame

Awesome experience wading/swimming thru cave system - We got picked up at our hotel on the Riviera Playa and transported to this eco tour. Unfortunately there were multiple stops for both the trip over there and back so this added considerable time to the day experience. However, once in the cave/river system you forget all that since it is magical. Walking thru the car system, thru water which is clear and sometimes chest deep and sometimes ankle deep and multiple times you have to swim. But no worries, wetsuit and lifejacket and helmet with light is provided. I loved every minute of this unique trip in the water/cave. Now, if you have difficulties walking, this is NOT your trip.. footing is uneven and slippery. And you have have to have a basic level of fitness or you won’t it. And take the wetsuit, the water is COLD after you have been going thru it for that long. It’s about 1.5 hour thru the cave/water, we saw bats and fish. And on the walk over to the cave entrance we saw a spider monkey! Be prepared for a rough ride to the entrance station where you get your wetsuit etc. There are showers and changing rooms and lockers

Superb outing to make... - Superb outing to make with family. Fascinating excursion with a guide at the top who speaks very well French "Benito". Critical point, we are not allowed to take our phones or any other cameras/videos. We have a photographer who is attracted to the group. Then you go to the painful a. 30 dollars a photo/100 dollars the five/135 all photos! 🥲

All right. - Overall very well. The guide, Tainara, very nice and explains everything very well. The site is a pass, they keep it very natural, without apparently much interference, respecting the rock formations and the environment. Then the buffet well, it doesn't have much variety but you step out. The only one hits the transport, you leave your cervicals with no suspension, and I don’t just talk about the route of the dirt road.

No show! - Yes, they’re refunding my money, but that still left us with an ‘All dressed up and no place to go’ experience. Super frustrating that the phone numbers I was provided all were dead ends.
