Black Rock Foreshore
Picnic at Black Rock, Portskewett, between the two Severn Bridges. There's a new Coastal Path that runs through the Black Rock site and goes all the way round the Welsh coast I think. We went down onto the shore by the picnic site and found a HUGE roll of greaseproof paper washed up on the rocks! This fence has seaweed caught all over it from when the tide is really high.
