Very cool mostly cave/underground cenote that is quite popular.

One of the most popular cenotes in the region offering many activities. Set aside around 2 or 3 hours total. It's M$350 as of July 2017 for entrance with your own snorkeling. There is a small local restaurant with local dishes for M$70 (Feb 2022). It's at the intersection of the Highway 307 and the road to the cenote, between the minimarket and the ticket booth. They serve lunch until 15:00.
Here the Cenote goes underground 90 m (100 yards) before the beach, and emerges as an 'underwater' water spring about 18 m (20 yards) of the beach in the ocean. Tanka III Bay is 7 km (5 miles) north of the intersection to the ruins. Take a cab. Great places to eat and stay or scuba too. One of the ways to make sure you also visit and dive is to arrange taking a diving course there and it will take just 3 hours in total.
