Mumbles marks the start of the Gower Peninsula, where a Victorian pier stretches into the Swansea Bay tide. This former fishing village is famous for its oyster trade and the lighthouse on the outer island. My top tip is to visit Oystermouth Castle above the village. You can walk the stone ramparts for views of the coast for free. The scent of salt and traditional ice cream drifts through the narrow streets. Local boats still land fresh seafood near the lifeboat station. Life here is tied to the movement of the sea and the lively promenade. It is a brilliant spot for a break with dogs welcome on the paths toward Langland Bay.
