This pebble beach at Cold Knap about a 5 minute drive west of Barry Island is a very popular fishing venue. Car Parking as you can see below is very good although it can become busy in the summer months. Toilet facilities are quite good and at my last visit there was a refreshment van selling beefburgers drinks etc. There are some good walks around the lake and across to the headland.

To the left of the above photo can be seen the beach at Porthkerry Park, which is also popular for picnics owing to large expanses of parkland and woodland (Photo Below)
