If you like canoes/kayaks, this is a great place for you. It is situated 1 hour by car from Ouistreham(where there are ferries going to Portsmouth). You can choose to row for 7, 14, 20, 25 or 28 kms. It is very relaxing. The maximum I have done is 14 kms and it’s quite easy to do. You’ve got plenty of time to do it and you can stop at anytime on the riverside for a picnic. The river level is always very low and the current is not strong at all. But there are a few small waterfalls to spice up the journey. Price range for 7kms and 14kms is EUR16-EUR45.
