It's the best for a Reason...

 

Theres no way around it...The Cayman Islands are a Divers ultimate mecca for a reason.  The three islands are limestone outcroppings, the peaks of a submarine mountain range called the Cayman Ridge, which extends west southwest for the Sierra Maestra range off the southeast part of Cuba to the Misteriosa Bank near Belize.  These island lack any sort of rivers or streams due to the porous nature of the limestone rock.  It is this lack of runoff which gives the surorunding Caribbean Sea exceptional visibility, often times well over 120 ft.

Between the Cayman Islands and Jamaica lies the deepest part of the Caribbean, the Cayman Trough, which is over four miles deep.  South of Cayman is the Bartlett Deep where depths of over 18.000 ft. have been recorded.  All three Islands are surrounded by healthy coral reefs which lie at the top of dramatic walls and drop-offs close to shore, this all creates ideal conditions for diving and sportfishing.
