Geography & Wildlife

Between the agoutis, the endemic blue iguanas and the abundant bird and plant life - you're sure to be impressed with the flora and fauna the Cayman Islands has to offer.

Grand Cayman is the largest of the three Cayman Islands, and is about 76 square miles and approximately 22 miles long by four miles wide. The Island’s famous North Sound, a shallow reef surrounded by clear aquamarine water, is about 35 square miles and is abundant with marine life and stunning coral. Although Grand Cayman is a low lying island with wetlands filled with diverse bird and marine life, there is an exceptional dry-wood forest called the Mastic Reserve & Trail (one of the few remaining in Grand Cayman) towards the eastern part of the Island.

Cayman Brac, the second largest of the Cayman Islands, has a 140 foot bluff. Being the Island’s most striking feature, it is known to eco lovers for its numerous hiking trails, caves and rock climbing hotspots.  Little Cayman, the smallest and least developed of the Cayman Islands is a sleepy little island teeming with vibrant marine life.

While the diving on Little Cayman is renowned all around the world, the Island’s Booby Pond Nature Reserve (a site with international designation) is known to avid birders around world. Cayman Resident also has good recommendations on what to do on this Robinson Crusoe hideaway plus where to stay!

Read on to find out the actual depth of Cayman’s very own “abyss” plus how close the Islands are to the Oriente Transform Fault.


Geologically speaking, The Cayman Islands are actually the tops of seamount pinnacles reaching up from the Cayman Trench – one of the deepest sections of ocean in the world.


Hidden away under the jagged crust of Grand Cayman’s East End and the craggy cliffs of the Bluff in Cayman Brac, lie beautiful and mysterious mineral deposits called Caymanite. These rock strata are found only in the Cayman Islands and are well disguised by the surrounding limestone.

Flora & Fauna

Cayman is world-renowned for its marine life, but there is much to see on land as well. Over 650 different species of plants have been recorded and the forests are far more diverse than those found in more temperate northerly latitudes.


Before the Mosquito Research and Control Unit (MRCU) was established in 1965, mosquito numbers were legendary. Reports were made of livestock being suffocated during the night and people did not venture outdoors without a smoke-pot to drive off the mosquitoes.
