I recently travelled to England's national water sports centre(HPP) in Nottingham. You can do lots of different types of water sports but I went over for their white water course which is 700 meters long. It is a great place for freestyle kayaking with 5 quality play holes along the course. You can throw down most moves you can think of. And there is a campsite straight across the road from the entrance. I would recommend people who are into freestyle if they're ever paddling near England to take a trip to this place.
