Three Marys Cays are three limestone ironshore rocks found close off the north coast of North Caicos. The general area is quite scenic and uninhabited, making it a popular spot to visit for day trips, picnics and
Like much of the coastline on the island, water conditions are typically mild and perfect for swimming. There can be a little floating seaweed at times, but rarely enough to be bothersome.
When in the area of Three Marys Cay, nature enthusiasts will appreciate the saline wetland of Pumpkin Bluff Pond, Moore Hall Pond, and Mud Hole Pond. These systems support a wide range of wading and coastal bird life, including great herons, yellow-crowned night herons, tri-colored herons, reddish egrets, great egrets, ospreys, and several types of ducks.
Groves of the hardy thatch palm (Coccothrinax inaguensis), which is endemic to the Turks and Caicos and Bahamas, can be found along the coast west of Three Marys Cays. These little palms offer scenic patches of shade.
Three Marys Cays are protected as a nature sanctuary, and it is a criminal offense to remove anything, litter, or otherwise damage the cays.
The snorkeling from shore on North Caicos isn’t great compared to the other main island in the country, however, this location is the best easily accessible spot on the island and small amounts of coral, small colorful reef fish and the occasional stingray can be seen.
Conditions here vary and on some days it’s totally unsuitable for snorkeling due to poor visibility caused by wind light surf. Check our
wind forecast for a prediction of the conditions. Generally, if the breeze is less than 10 knots (18kph), the ocean will likely be calm and clear.
As is exhibited on many of our limestone coasts, the rock of the cays has been undercut by the action of the ocean to the high tide point, and in places overhangs almost 12 feet (3.6m). Chitons molluscs and sea urchins make the ledges and crevices their home, and add to the underwater menagerie.
Due to the overhangs, it’s actually quite difficult to climb onto the cays and due to the sharp limestone, you can be seriously injured.
