Cruise to Denver Lock where the complex controls river levels for the area, craft passages and export of water to Essex. Many spectacular walks are sign posted in the area.
Lock onto the relief channel where you can enjoy no speed limit and cruise to the end at the sluice to the Tidal Ouse. A handy pub is located halfway down and makes a nice stop.
Lock onto the Tidal Ouse (consult lock-keeper) and follow the river down to Kings Lynn.
Enjoy the Kings Lynn waterfront bars and restaurants. The fish quay is active with the tides and the quaint local streets make interesting exploring.
Alternatively head on out to the Wash for some real sea boating and the ability to connect to the Norfolk Broads, Ipswich etc.
There are many old and interesting buildings at the waterfront, such as the Harbour Masters Building above.
