The Derwent Valley Heritage Way (DVHW) is a 55 miles (89 km) waymarked footpath along the Derwent Valley through the Peak District. The walk starts from Ladybower Reservoir in the Peak District National Park via Chatsworth, the scenery around the Derbyshire Dales, and through the Derwent Valley Mills World Heritage Site. It follows the Riverside Path through Derby and continues onwards to the historic inland port of Shardlow. Journey's end is at Derwent Mouth where the River Derwent flows into the River Trent.

Derwent Mouth is a location on the River Trent, which at that point forms the border between the English counties of Derbyshire and Leicestershire. It is both the confluence of the River Derwent with the River Trent, and the point at which the Trent and Mersey Canal joins the natural River Trent.
