Hallelujah Bay is a bay located on the west side of the Isle of Portland, Dorset, England. The bay is situated below West Weares, with Clay Ope, Blacknor Point and Mutton Cove further south. Near the cove is a large mound of rock and earth beneath the clifftops known locally as the Green Hump. The official public right of way leading to the bay has been subject to landslips over the decades. In 2014, the path was officially closed by the council due to landslides and falling rocks.
