Apparently due to the works ongoing at Folkestone Harbour, the truck parking will close in April and there are no plans to reopen it.
Shame, that is definitely one of the best spots in the UK to park, good pubs and places to eat within a 5 minute walk.
There used to be a smaller lorry park in the town, but it filled up quickly.
As you came up the one way high street / main street it was in the fork at the top.
Is it still there? Maybe it has been redeveloped - long time since I’ve been there.
