This is a small company offering kayak hire on the River Dee.  Rather than just paddle around the groves area, you actually book a "trip". They take you to start point outside the city, and you paddle downstream to the city centre.  They meet you at the other end when you have finished your trip.  Hire a kayak from a couple of hours (5 mile trip)  to a full day (12 miles). All equipment and transport is provided.
