.....pool/lake/river swimming
cycle tracks nearby
fishing on site
watersport hire (canoe/windsurf)
no big entertainment on site
not too far from town/village/shop ( cyclable distance)
And max. 7/8 hours from Calais ideally.
Or at least most (or some) of those!
Loved Noirmoutier (indigo site) and Loire (prunay.fr/en/)
Thanks!
