Yal Ku Lagoon

Yal Ku Lagoon is a renowned snorkeling spot located amidst a gorgeous environment. It is composed of a small bay and a set of shallow pools sheltered from waves and currents, making it an ideal place for snorkeling beginners. Aquatic life isn’t thriving here (few species do appreciate the fresh water pouring in from Cenotes rivers) and the entrance cost is quite high, but this uncommon place is still worth a visit. Don’t hesitate to add Akumal Bay to your snorkeling day, it is located 1.5 km from Yal Ku and sea turtles are to be seen there.
How to get there?

Yal Ku Lagoon is located 1.5 km from the small village of Akumal, about 35 km South of Playa del Carmen and 25 km North of Tulum. If you’re driving, take “Akumal” exit from federal road 3017 and head to the village. From there, the “Yal Ku” signs will easily lead you to the park entrance. If you prefer public transportation (collectivos or more classic busses), the nearest stop is “Akumal”. Busses don’t stop closer to Yal Ku: consider taking a cab from Akumal.

The entrance fee to the lagoon is 14 dollars (200 mex. pesos) per person for a whole day. You can bring your own snorkeling gear or rent it on site. Please note that the use of sunscreen and mosquito repellent is forbidden in the park in order to preserve the fragile marine environment.

Water entrance

The site is equipped with numerous stairways for a safe water entrance; many of them are located close to the park entrance.

Aerial view


Yal Ku lagoon is perfectly fit for snorkeling: its shallow waters (3-12ft/1-3m) are sheltered from waves and currents. The site is made of a bay and a network of channels fringed with rocks and mangrove swamps.

Start with the exploration of the small (only a few meters wide) rocky pools connected to each other. This area, close to the entrance and easily accessible through the stairways and ladders set on the shore, is logically the most frequented and water is often troubled. Swimming forward from here, you will come to the less frequented heart of the lagoon (2-3 m). Beware tidal currents that can sometimes appear in the area.

Underwater life at Yal Ku Lagoon

The seabed is mainly made of large smooth rocks, sometimes covered with seaweed. Fringing some areas, mangroves add an original touch to the landscape. You will spot a lot of fish in the lagoon, but few different species dwell here. You will mainly see stripped sergeant-majors, sometimes only a few centimeters underneath the water surface. Mullets, bermuda chub and garfish (hunting right underneath the water surface) are also amongst the most frequent species to be spotted here. A little less frequent but still easy to spot are blue surgeonfish and doctorfish tang.

The lagoon being a place where fresh and salt water meet, visibility can be poor in some places. A lot of snorkelers here are beginners: beware collisions and fin strokes!

Restaurants and accommodation

There is a snack bar inside the park. Numerous options (restaurants, convenience stores and hotels) can also be found only 1 mile from here, in Akumal.
