If you're heading straight from the ferry terminal to the motorway south, then this is the first chance for the pooch to do a bit of scratching and sniffing on French soil.
Motorways in France have 'Aires du repose' at regular intervals and, while this is not the most glorious one and it is not suitable for off-lead exercise, there is at least a bit of grass. Picnic tables. WCs and easy access for people towing a caravan.
WCs - always a good idea to have your own supply of loo paper...
How to get there
The Aire de Zutkerque is between junctions 1 and 2 on the southbound route of the A26.

This is just an emergency stop. With some grass.
