Waterlemon Cay Tours and Activities

The tiny island of Waterlemon Cay on St John is a favorite among snorkelers. The sandy beach of Leinster Bay serves as the starting point for a 10-minute swim to Waterlemon Cay; it's less than a mile to the island and worth every breaststroke. The cay is home to a wealth of coral and marine life, which is what ranks it so high with travelers. Sadly, the island has seen a recent reduction in coral and reef fishes, attributed to high rates of erosion and run off from local construction.

During the swim, keep watch in the sea grass for the first glimpses of marine life in the area. It’s not uncommon to see turtles, stingrays, sea cucumbers and giant starfish 20 feet below.

The south- and east-facing sides of Waterlemon Cay are bordered by the region’s shallow fringe reef, whereas the west and north sides are deeper. The reef is the best spot to look for the main abundance of colorful fish and other marine life; look for large parrotfish and schools of bright blue tangs. Some snorkelers swear they can hear the crunch of parrotfish “teeth” as they grind their beaks on rocks and dead coral at the surface. Turns out parrotfish digest coral and algae that are ultimately excreted as fine coral sand, helping build the beaches we love so much.

Snorkelers will find a lot of colorful coral, sea fans, sea plumes and other colorful fish on the deeper side of the reef. Keep your eye out for eels in deep holes and you may even luck out and see an octopus or two.
