I take it you'll be sleeping in the Van...."Hopes Nose" was always a favourite in times gone by....but wouldn't be advisable leaving the Van with Boat attached these days!....As its some way from the road
The local community even pay for Private security patrols from thier own pockets! .... as "Very-non local" elements proliferate and congregate in the area above the Spot ...which has lead to many problems.
If you're stuck for parking and somewhere to stay ....why not ask around in a local ..better still "Country" Pub close by if you can use thier Car park overnight?...something we have done with good results in the past....and is a growing trend with Motorhomes....I even think there is a website.
A few Pints or some food usually suffices for payment
....but even if you have to pay a small fee it'll be safer and quieter without the chance of being turfed out or moved in the early hours.
