Laguna Yal-Kú, Akumal
Overview
Laguna Yal-Kú is a lagoon at the north end of Akumal, on the Riviera Maya between Playa del Carmen and Tulum, where fresh water from the underground river system flows out to meet the Caribbean. The mixture of fresh and salt water creates calm, clear, brackish water with a large population of tropical fish, and the lagoon is one of the best-known snorkelling sites on this part of the coast.
The lagoon is managed as a park, and visitors pay for entry. There are two entrances, run by separate operators, which give access to the same water. The banks have palapas, hammocks, showers, changing rooms, a restaurant and a garden of stone and bronze sculptures. Snorkel equipment and life vests can be rented at the entrance or brought from home.

Photo summary of last month
Each photograph is published unedited and in date order, and is replaced as newer submissions arrive, so what appears here is the most recent view of the beach rather than a promotional photograph.
Yal-Kú is an enclosed lagoon rather than an open beach, so its photographs are a useful comparison with Akumal Bay, Half Moon Bay and Xpu-Ha on the same day.
Position relative to the Atlantic sargassum belt
Sargassum is carried north along the Riviera Maya by the Yucatán Current and pushed ashore by the easterly wind, and Akumal, on the southern part of the coast, often receives it early in the season. Yal-Kú is an enclosed lagoon that opens to the sea through a narrow mouth, so it is far less exposed than the open beaches on either side. It is not sealed from the sea, however, and the dated photographs above show its actual condition.
The sargassum season
The regional season runs from roughly May to August, with the heaviest arrivals usually in June and July, and the coast is generally quieter from late autumn into spring. The wider picture is set out in our Riviera Maya sargassum season guide.
Snorkelling and the rules of the lagoon
The lagoon is between about one and a half and four and a half metres deep, with parrotfish, other reef fish and, on some days, turtles and rays. Life vests are required in the water, and diving down is not permitted. Ordinary sunscreen, tanning oil and insect repellent are not allowed, in order to protect the water, and feeding the fish is prohibited. The early morning and the late afternoon are usually quieter than the middle of the day, and Sundays are generally the busiest day.
Swimming conditions and safety
The water is calm and free of waves, which makes the lagoon suitable for children and beginners. A current runs in parts of the lagoon where the fresh water flows towards the sea, and the rocky edges call for care when entering and leaving the water.
Access and getting there
Yal-Kú is at the north end of Akumal, reached by the road that runs north from the main Akumal entrance on Highway 307, about 37 kilometres south of Playa del Carmen. Colectivos running between Playa del Carmen and Tulum stop at the Akumal entrance on request. Opening hours and entry prices change from season to season and are best confirmed with the operators before visiting.
