Little Cayman is bracketed by lighthouses at the West and East Ends, whose terrain couldn't be more different. The semiarid East End has a remote, end-of-the-world feel: Limestone sinkholes called karst stitched with xeric shrub give it a pitted moonlike appearance. The West End is much greener. But beaches, snorkeling, nature trails, and bird-viewing areas embroider the entire island. One main road, mostly paved, essentially circumnavigates the coast. Several packed-dirt side roads crisscross the island, often accessing the more remote beaches. These can become muddy and almost impassable in heavy rain.
