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

Perfect Day - Fantastic tour of the Suprema cave led by Martin. Martin spoke fluent English, Spanish and French during the tour. His ability to blend his knowledge of hard science with ancient Mayan beliefs was terrific. We loved the tour.

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.

Cave Energy, shifting times - I Really enjoyed All the rio secreto plus ticket activities which included bike riding repelling down in a cenote, 3 zip lines, a really bouncy swing bridge and cave viewing / spelunking/ swimming, wading, scrambling, crab walking , ducking, crawling, floating and so on Our guide Miguel was excellent, informative and helpful with a hand to balance at any time I needed it. I enjoyed the Mayan ceremony of blessing and Welcome We saw so many things today ... a spider, gecko, coate, iguana , 6 different butterflies, huge dragonflies, bats, birds, an orchid, all sorts of plants and even a cat. Note: be careful if you book online as a plus ticket can and did show up as a regular one for some odd reason, luckily I put my ticket in my digital wallet as proof. Also, always book with a transfer unless you have a car it was 450 pesos each way which is almost 80$ from where I was staying ... Which is fine if you have mucho dinero.But, if you don't, then that is an extra cost you don't really need. They have lockers for your stuff and all the gear...my bike( hard to ride) and lock sure needed oil (hard to open) and the food was barely passable in the buffet just some fruit, meat options sauce, and pasta... Our guide kept talking about tacos....but there was none to be had ...the hibiscus drink was good.
