A ruined castle above Swansea Bay, open seasonally (April to October) with entry paid on the gate rather than booked ahead. It's smaller than its reputation suggests, reviewers say, but the walk around the walls and the views over the bay hold up well for the modest entry price.

The walk along the castle walls, with views over Swansea Bay that reviewers say exceed expectations for the size of the site.
Before you go
Parking nearby is limited, so allow time to find a space; the gates don't open until 11am, and the toilets get consistently poor marks, so plan accordingly.
Visitors consistently enjoy walking the castle walls for the views towards Mumbles and Swansea, and several specifically mention it as a dog-friendly, welcoming site with helpful staff. Parking near the castle is repeatedly flagged as limited and hard to come by, and one reviewer singles out the toilets as being in poor condition. Overall the reviews are strongly positive despite these practical niggles.
