Brampton Valley Way, Kelmarsh
Northamptonshire
The Brampton Valley Way follows the trackbed of the old Northampton to Market Harborough railway for 22.5 km end to end, but the Kelmarsh section is the most rewarding stretch for a dog walk. From the old station car park, the out-and-back route heads south through open Northamptonshire farmland, crossing bridges over the infant River Nene and gradually narrowing as it approaches the Kelmarsh tunnel — cool, unlit, and dripping, with a strong echo that surprises most dogs the first time. The gravel and earth surface drains reasonably well and dogs can be off-lead for the full length once away from road crossings.
Red kites are a near-constant overhead presence on this section. The scent along the corridor is that particular combination of old iron ballast, warm dry verge grass, and in summer the faint sweetness of meadowsweet along the field edges — unmistakably a railway path. The Northampton and Lamport heritage railway runs alongside part of the trail, adding an occasional steam-engine encounter.
