Coined the 'Sanctuary of Life' from the locals, the Tsukan cenote cave is steeped in natural wonder. In fact, it's been mainly untouched from how it was originally found, with the only addition being a proper staircase to access the pristine water. Enjoy time swimming, relaxing and lapping up the traditional side of Yucatan. A three-course lunch of regional classics is included, washed down with water.
