Two for you to have a look at here. Whilst they aren't proper wild spots, they are free overnight parkings. 1) Wallasey There is ample road side parking along the sea wall just off the A554. Great views of shipping coming and going and a long beach to walk along (wind permitting!) 2) Parking on a small carpark overlooking the river Dee estuary alongside the sailing club at Thurstaston. Lovely walks along a disused rail track to West Kirby. Both found on Camper Contact.
