Yal Kú Lagoon, Natural lagoon in Akumal, Mexico
Yal Kú Lagoon is a natural lagoon in Akumal where fresh water from underground cenotes blends with Caribbean saltwater, creating a shared habitat for both freshwater and marine fish species. The lagoon covers a compact area surrounded by limestone cliffs and mangrove vegetation at its edges.
The lagoon served Maya communities in the region for centuries as a source of fresh water from underground springs. It functioned as a sheltered water source connecting inland settlements to coastal trade networks.
Local environmental groups maintain a collection of stone sculptures along the lagoon's edge, representing the connection between marine life and Mexican artistic heritage.
The lagoon offers easy entry from the shore with shallow access points and snorkeling available directly from land. Equipment rental and storage facilities are available on-site to help visitors enjoy the water safely.
The lagoon stays shallow at under 4 meters deep throughout, making it especially safe for snorkelers and allowing views of the bottom from many positions. Underground limestone channels create natural pathways where fresh and salt water meet, forming a visible boundary between the two water masses that you can observe while swimming.
