we stayed at one in Bashley, run by Mr and Mrs Kitchener, they are in the big sites book. Nice site and loo and shower. About 7 vans only and just outside New Milton. Not in centre of New forest but a two minute drive to the start of it. Can't remember the name but it does have one.
The site is at rear of their grounds in a large field with an orchard one side, horse field at rear and deer and rabbits. Very quiet and does get booked up but not sure if open all year and my book is in the van. There are a few CLs around there I know.
A day of all things motorhome and campervan. The show is held both in the main indoor arena and across the grounds. Catering, hot drinks and food options are available. Easy access to the site and free parking included. Win one of five pairs of day tickets
