We love this walk. We can go for a stroll over the barrage. Meet the Penarth Marine end, then we'll stroll over to the park and back. You have to pay for the car park. Bus routes near by or ask for a car share in comments. Buggy and wheelchair assessable. Its about 1-2km. There is a new cafe that has opened at the start of the walk. We will meet just by the bridge at the entrance to the barrage, basically in the car park. If you need a postcode then the Custom House takes you opposite the car park Penarth CF64 1TP.
