Swimming is not allowed.
On this page you find a daytrip of 22 km starting at the kayak rentals of Isnor in the village Clairmarais. And another daytrip of 16 km that begins in Houlle (no kayak rentals here). No portages at all.

In September 2012 I visited the Clairmarais in the department Nord Pas-de-Calais with my son. There is a camping site Camping Clairmarais, nearby the starting point at the kayak rentals of Isnor. We stayed at the bed-and-breakfast Pantgat Hof, though. It is situated near Bollezeele, about 20 km from Clairmarais. There are more accomodations in the area. You can find them on www.booking.com. Finding a place to eat is more difficult: during the week most restaurants are closed. And if they're open it's only the bar and they don't serve meals. In Saint-Omer there are some restaurants along the main square in the city center (Place du Maréchal Foch) that are open every day. We had a good meal in the center of Dunkerque at Bellevue, Place de la Gare 1.
