Cemlyn Bay Coastal Path Loop (Bryn Aber)

Cemlyn Bay sits on the northern tip of Anglesey, a rugged, wildlife-rich stretch of coastline where a shingle ridge separates a brackish lagoon from the open sea. This 5 km circuit from Bryn Aber car park follows the coastal path with sea views almost immediately, tracing the bay past the lagoon where terns breed in summer and wading birds work the shingle in winter. The 50 m of climbing is negligible, and the terrain is straightforward coastal path throughout. The landscape feels properly wild, with the lagoon, sea cliffs and open water creating a dramatic backdrop that changes constantly with the light and tide.

This is a dog friendly walk with strong sensory appeal. The salt air, seabird activity and tidal scent from the lagoon keep dogs alert and engaged, and the open coastal paths provide space and wind. Off-lead potential is limited as livestock graze some of the surrounding fields and the lagoon is an important wildlife habitat, particularly during the tern breeding season when dogs must be kept away from the shingle ridge. Leads should be carried and used where required by seasonal signs. The easy terrain suits dogs of all fitness levels, and the compact distance makes this a practical outing that still delivers genuine coastal atmosphere. Best visited outside the breeding season if you want maximum freedom for your dog.
