Grenada’s best-kept secrets



We continue our series of blogs from the Aquanauts Grenada team, this time focusing on the diving around the uninhabited islands of Grenada.

As divers, we love exploring places that others have not. The hidden gems that you continue to talk about for years. The special dives where you get lost in a world of color and intrigue. Grenada offers this special treat to divers who yearn for adventure!

Off the north coast of the island of Grenada are a collection of uninhabited islands that hold the ultimate combination of serenity and thrill – Isle de Caille, Isle de Rhonde, Diamond Rock, and Sisters Rock are a few of Grenada’s best kept secrets.


Due to the lack of human activity in the area, fish populations thrive and the coral reefs are vibrant. The reef formations around each island have a distinct feel, each a little different than its neighbour. Not far from Kickem’ Jenny, an active underwater volcano, divers occasionally hear its rumbles and cracks. During whale migration season, divers can also sometimes hear whales communicating within their pod.

Isle de Caille is the most exposed area to the currents of the Atlantic Ocean. While not always accessible due to weather, this represents a breeding ground for leatherback and hawksbill turtles as well as many species of sharks. It’s a relatively flat reef with a depth ranging from 13-21m.


Isle de Rhonde is less exposed, but can still offer sporty drift dives as it has a sloping reef ranging from 10-36m. The fish populations are vast including big rays, green moray eels, turtles, and nurse sharks. The coral ranges from beautiful fans to soft corals that give the sense of a windy day. Out on the sand patches, you can see the ‘champagne bubbles' from Kickem’ Jenny.

Diamond Rock sits at the north end of the island chain. The leeward side of the island is typically calm with softer currents than the other two islands. It also has a more gentle sloping topology with hard corals mixed in which eventually leads to a stunning wall. The wall has a split in the middle which is wide enough for divers to explore and find the hidden creatures including large crabs and moray eels. The depth ranges from 5-33m.


Sisters Rock is at the southern end of the island chain and has an underwater cavern. The cavern has two entrances and an air pocket. The air is filtered by a hole in the top of the rock so divers can safely remove their regulator and view the rock formations inside. After the cavern, the current will either guide you to the right which leads you to a nice sloping reef with a max depth of 21-24m or to the left which has a beautiful wall extending farther than the eye can see. A mesmerizing place where you get lost in the presence of nature’s beauty and strength.

To explore Grenada’s best kept secrets are an all-day adventure, and you’ll leave wanting to return for more!
