River Derwent Mountain Bike Routes

About River Derwent

The Derwent is a river in the English Lake District, with its source at Styhead Tarn near Skafell Pike and its mouth at Workington on Cumbria's west coast.

The river meanders down the Borrowdale valley and flows into the southern end of Derwent Water. Exiting near Keswick it then heads west and flows into Bassenthwaite Lake and from there to Workington via the town of Cockermouth.

Mountain bike routes along the Derwent are mostly limited to near its source and the Borrowdale valley. Here is what we have.

This classic Lake District mountain bike route starts and ends in Keswick and performs a full loop around the picturesque Derwent Water and Borrowdale valley. Despite being reasonably easy effort wise, the Borrowdale Bash includes several miles of wonderful technical singletrack and beautiful views across Keswick, Derwent Water, Skiddaw and the fells beyond.

As mentioned the route starts in Keswick (making it easy to access directly from the A66). The first leg takes the road south along the east bank of Derwent Water before climbing into the fells past Ashness Bridge and towards Watendlath Tarn. Birkett's Leap then drops you back into the Borrowdale valley and climbs the other side where it descends once again, flanking High Scawdel and returning north to Keswick via the Allerdale Ramble high above the west bank of Derwent Water.
