Once you find the tres trapi steps just east of Boca Catalina beach you will happy you did, easy to get up and down steps, water is beautiful and snorkelling in three directions. Turtles are straight ahead  and starfish to the left , go to the right and larger schools of smaller fish and many other fish in between. Water is a bit deeper once you get out from the little entry beach at the steps, but can walk beside the iron shore before you swim out so don’t have to swim far out really, just float around. Definitely on out top spots to snorkel now
