Marsworth Reservoir

Highlight • Lake

The Marsworth Reservoirs act as a magnet for anglers, dog walkers, boaters, birdwatchers and walkers, especially over a sunny weekend, but few ever really venture much beyond the car parks …

Stone Bridge on the Grand Union Canal

Highlight (Segment) • Bridge

This section north of Berkhamsted gets very narrow in places - barely wide enough to ride along. Take your time.

At the point the Grand union is a good ride; wide enough and smooth enough for quick progress. Further north however...:-S
