Intermediate Cayman Islands
Little Cayman
A wall that starts at six meters and drops two thousand, on an island with more iguanas than residents
The wall starts at six meters. You cross a shallow lagoon of white sand, pass a coral crest, and the bottom disappears: a two-thousand-meter drop beneath your fins, with thirty to forty meters of visibility to see it.
In this guide you'll find out why this tiny island has one of the most cited walls in the Caribbean, how the diving works, what happens with the Nassau grouper spawning aggregation in winter, when to go, and what rules keep it that way.
It's proof that early protection works: an island with a minimal population, few dive slots, and strict rules has kept a wall and a grouper aggregation that were lost everywhere else in the Caribbean.
Geography and access
Little Cayman is the smallest of the three Cayman Islands, with a permanent population of a few hundred people and deliberately minimal infrastructure.
The island is the summit of an underwater mountain: the island shelf is extremely narrow, and the terrain drops toward depths of thousands of meters just a short distance from shore.
On the north coast, that drop forms a wall that begins between five and eight meters, after a shallow sand lagoon and a coral crest.
The lagoon acts as a filter: it retains sediment and lets very clear water flow through to the wall, which explains the visibility.
At the western end there's a spot where one of the last large Nassau grouper spawning aggregations in the Caribbean gathers every winter.
Access is a short domestic flight from the archipelago's main island, on a small plane with limited seats.
