"If you have any reservations, I urge you to book this. I've been on many excursions in many locations including Laos Thailand, Cancun, Cabo, Isla Mujeres, Riviera Maya, the Dominican Republic, etc. and this is the best excursion I've ever booked. We went to 3 cenotes and had a personalized and safe experience in each. The guides not only told us about the history of the cenotes but also taught us how to swim in them since there's sodium bicarbonate in the water which makes you feel like you're swimming slower. The guides taught me how to relax my body and hold my breath for longer so that I could swim to underwater air pockets in the caves. And the last cenote had a platform to jump off of which was so much fun. This excursion can either be as easy or as intense as you want it to be- my friends didn't do as much jumping and cave exploring as I did. This trip is catered to any level of ability- whether you want something more intense and exploratory or something more chill. The guides were super friendly and had many stories to share. At the end we ate authentic mexican food which was the best food I had on my entire trip- no joke. And we purchased the photos at the end for a great price, given that they took hundreds of photos and videos of our group."
