What a brilliant site.  After completing 3 months travelling through France, Spain and Portugal we booked La Hallerais as a night stop prior to catching the ferry the following day - mistake!  Of the 22 sites we used this site was definitely in the top 3 and having experienced the peacefulness, the superb layout of the site, the friendliness of the reception and restaurant staff, the cleanliness of the facilities and the proximity to picturesque Dinan,  we wished we had booked for longer.  If, like us, you are towing a trailer it is best to approach the site from the north and not,  as we did, through Dinan.
