The Bluff is the limestone spine that runs along the eastern two-thirds of Cayman Brac, rising gently from the west and ending in a sheer 43-metre cliff at the eastern tip. It dominates the island physically and culturally — almost every map of Cayman Brac is oriented around it, and locals talk about "up on the Bluff" or "below the Bluff" the way other places talk about districts.
Several signposted hiking trails cross the Bluff: the Lighthouse Footpath at the eastern end (a 30-minute walk to the lighthouse and a vertiginous cliff edge), the Heritage Trail across the top, and the Bat Cave Trail near the centre. The Cayman Brac parrot reserve is on the Bluff and the trails make a reasonable chance of spotting the endemic subspecies. The rock-climbing routes are bolted into the south-facing cliff and rated as some of the best in the Caribbean; equipment can be rented through the Brac Reef hotel.
