The lockers at Xcaret are fine, but anything you want ON you during the float needs to handle full submersion. I lost a pair of sunglasses and nearly killed my phone before I wised up.













You're underground part of the time, but the open stretches between cave sections are brutal. I got the worst burn of my life on the back of my knees because I thought the caves would keep me covered.













Flip-flops are a trap. The entry and exit points for the underground rivers have algae-covered rocks that will put you on your back faster than you can say “vacation injury.”













The park is massive and the food lines get long after 1pm. I made the mistake of not eating before my second river float and nearly bonked halfway through the longest stretch.













Cotton is the enemy. I wore a regular t-shirt my first time and it got heavy, cold, and took four hours to dry. The underground sections are cooler than you'd expect.













There are multiple river routes and most people just wander into whichever entrance they see first. Bad move. The order you do them in changes your whole experience.











Nobody warned me how tired I'd be after six hours of swimming, walking jungle paths, and baking in the sun. The drive back to the hotel was rough until I started packing recovery stuff.
