Yal Ku is a lagoon formed from where the fresh water from underground rivers, called cenotes, broke through the land and formed a channel to the Caribbean.
It is a wonderful place to snorkel and while it does not have coral gardens, it has many large Caribbean fishes and sea birds, including the brown pelican. It also has beautiful rock formations.
Yal-Ku is a 2 minute walk from our complex, La Sirena!
There are now 2 concessions that charge admission, the original at the end, which is larger and has more facilities and a newer one to the left, which has day cabins for rental. As the entrance fee is for the full day, we suggest to visit Yal-Ku go early, then as the tour buses arrive around 11, leave and then come back later in the afternoon.
