About this beach

Watch House Bay is a small easterly facing cove at the entrance to Barry Old Harbour. Around 100m long, the beach is backed by a concrete wall and large steps to a shingle bank with sand/mud at lower tides. The beach is next to Cold Knapp point and faces Friars Point to the west towards Barry Island. The Watchtower at the northern end of the beach was built around 1860 as a coastguard station, behind the beach a Victoria promenade leads to Knapp gardens and Cold Knapp Bay.
