Wow, what an amazing experience. If you're looking for an awesome tour experience while visiting Tulum, 100% book with these folks. We were treated to a magical afternoon being taken on a truly awe-inspiring underground tour of a cenote and the limestone caverns. The Mezcal tasting afterwards was very cool and informative, and was served up with some tasty snacks as well! Also, I simply can't say enough positive things about our guides Andrea and Alejandra, they were the best. They even helped arrange for our driver to stop by a store where we could buy some Mezcal to take home with us!
