Hey folks, stopped here last night, there are no actual facilities, but you are right in the centre of town, a short walk from the Barbican(pubs, chippies, take aways). There is security, and it’s gated, the signs say trucks from 1800 to 0700, but they don’t mind you turning up earlier or leaving later. the cost is £6.00. not bad in todays climate.
Just follow signs to city centre, then you should see a sign for truck parking, on your left, turn here, straight over mini r/about and the entrance is on your right.
Full address is: Bretonside, Plymouth, PL4 0BG.
