Pistache
An amazing site to see
This is a wonderful place that is located right between Playa del Carmen and Tulum, right in front of Akumal, and three miles inland on the opposite side of the sea.
It is a place where you are guided through a dripstone cave of about 500 meters, where you end up at an impressive and indescribable (at least for me!) dome. Whenever I can I revel in this amazing place. Judge it all for yourself!
