Please see the link to this video on stingray handling guidelines from our friends at the Guy Harvey Ocean Foundation, made in collaboration with the Department of Environment (DoE):

The Stingray Sandbar and Stingray City in Grand Cayman’s North Sound are two of the most amazing wildlife interaction zones in the Caribbean and we want to keep them that way! Remember, you may only interact with the rays at the two designated Wildlife Interaction Zones (WIZs) of the Sandbar and Stingray City.

All commercial operators taking tours into the WIZ zones are required to obtain a permit from the DoE each year.
