Answer:
The topography of the Cayman Islands is very flat and as such there are no mountains. The highest point of elevation above sea level in Grand Cayman is some 60ft asl, in the neighboring Sister Island of Cayman Brac however, there is a large bluff comprised mainly of limestone that rises to an elevation of 145 ft asl. The bluff is a known site in the Islands for both beginner and advanced abseiling or rockclimbing.
