Our trip down the Gloucester-Sharpness canal was a bit of a revelation. I must admit I expected it to be pretty dreary, with little in the way of views or beauty. How wrong one can be! The canal is very interesting with lots of manned swing bridges, and some lovely views over the River Severn estuary. The old bridge keepers cottages are interesting, tiny places but with Doric columns at the front door.
We've moored up on the outskirts of the docks and have no intention of venturing further as that appears to be only if you intend to go out of the locks onto the Severn.
