Open Doors Free Weekend at Penrhyn Castle

A rare free day inside one of Wales' grandest historic houses, with quarrymen demonstrating slate-splitting all weekend and a Victorian Kitchen bake-along on the Sunday.

The wooded parkland and Rhododendron Walk are step-free and dog-friendly on leads, so it works as a buggy walk, a wheelchair-accessible outing, or a slow amble with the dog and a castle-view picnic.
