If you like the idea of a Huck Finn adventure but at a more leisurely pace, then head for the Netherlands. On calm Dutch waterways you can camp on a ready-made raft, steadily moored to a river bank.
Camping rafts are the latest in back-to-nature holidaying. Logs lashed together float on barrels; on this raft sits an A-frame timber shelter with smooth, plywood floor. The entrance is a tent-like double flap. There’s no electricity and no plumbing. It is rather like sheltering in an attic from a spectacular flood. Access to your haven is by Canadian canoe.
