Arch Beach

Arch Beach is a small coastal beach on Alderney, in the Bailiwick of Guernsey, with a sheltered and secluded character. Its calm setting makes it suitable for swimming, gentle paddling and family time by the water. The beach has a quieter feel than a large open bay, with the surrounding rocks adding to its enclosed coastal atmosphere.

The shoreline looks out towards two Victorian fortresses and a lighthouse, giving the beach a clear sense of place within Alderney’s historic landscape. These views combine with the natural setting to make Arch Beach appealing to visitors interested in both the coast and the island’s heritage. The beach is also close to Saye Bay Campsite and is linked to it by a small tunnel. An arch at one end of the tunnel provides the feature from which the beach takes its name.

At low tide, the rocks provide a route towards neighbouring Corblets Bay. The changing tide reveals the connection between the two areas, creating an opportunity to explore the rocky shoreline when conditions allow. Corblets is also associated with rock pools at low tide, while the beach itself offers a calm place for a swim or paddle.

Arch Beach suits families looking for a sheltered place beside the sea, swimmers seeking calm water and walkers combining coastal scenery with views of historic fortifications. Its appeal comes from its compact scale, natural surroundings and connection with the neighbouring bay rather than from facilities or organised attractions. The beach is an outdoor setting, so visits are centred on the shore, sea and landscape.

Located in the St Anne area of Alderney, Arch Beach forms part of the island’s varied coastline. It works well as a short coastal stop, a family beach visit or part of a low-tide walk linking the nearby bays. Care around changing tides and the rocky shore remains important when exploring between Arch and Corblets.
