This circular walk starts at the Gower Inn in Parkmill and heads towards the coast, taking in the ruins of Pennard Castle, the sweep of Three Cliffs Bay and the quieter sands of Pobbles Bay before looping back to Parkmill.
Check the tide and path before you go: the stepping stones across Pennard Pill can be covered at high tide or after heavy rain, and there are strong rip currents at Three Cliffs Bay, so do not swim near the bay at high tide. Plan your crossing so you can get back safely.

🥾 Route Breakdown
A). Gower Inn, Parkmill (start and finish)
Start at the Gower Inn in Parkmill. Check the pub and local signs for parking rules, and do not leave a car where it blocks the road or the pub’s own customers.
B). Pennard Castle
The route heads towards the coast to the ruins of Pennard Castle, set high above the bay near Pennard Burrows. The castle is sand-eroded and weathered, and it gives a first view of the bay below.
