At the moment to access parkgate ,go into Neston ,there are big signs saying road closed ahead … ignore them and drive down to the front .. you can then either stop or carry on it’s open all the way through . Get to boathouse pub and drive onto the old baths car park .park on the front .there will be birdwatchers and photographers there just ask what’s about .
Boathouse road is the one that’s closed so to get out do that in reverse .. I don’t think you can currently access Burton mere from parkgate either ,,
Another good spot is hoylake sea front at high tide for waders
