Porthkerry Beach reaches from Bulwarks Iron Age Hill Fort in the west to Bullnose Cliff in the east. It consists of a high shingle bank of limestone pebbles with some sand at low tide. Dogs are allowed at all times. Behind the beach is Porthkerry Country Park set in a valley with woodland on either side, and crossed by the stream of Whitelands Brook. An impressive stone railway viaduct (110 feet high and 376 yards long) dominates the park. The car park is attended during the summer, otherwise free. Access to the beach is a mostly level walk of about 250 yards along good paths. Facilities in the park include a small cafe with a decking area, toilets, picnic benches, children's play area, woodland walks and a pitch & putt golf course. The neighbouring beach of Cold Knap can be easily reached along the beach or via the cliff path.
