Shark-Ray Alley is a boat-access snorkeling stop just south of Hol Chan where the bottom stays shallow, sandy, and calm enough for close-up wildlife viewing. The appeal is not coral terrain but easy encounters with nurse sharks, southern stingrays, and turtles around the boat stop, usually on a half-day tour from San Pedro or Caye Caulker. It is a busy, guide-led stop, so timing, boat traffic, and respectful wildlife spacing matter more than depth.
