Reaching up to 70m in height the cliffs have numerous ledges providing nest-sites and above them is a narrow strip of grassy sward backed by an area of maritime heath which lies outside the reserve.
From Pierowall village, towards the north end of the island, turn west at the school, following the signs to Noup Cliffs. Turn left at the junction past Noltland Castle, following the road up the hill, eventually passing through Noup Farm. Follow the gravel road to the Noup Lighthouse where there is a car park at the reserve entrance. The gravel road to the reserve entrance should only be attempted in a 4x4 vehicle.
