Terrain:

The terrain of the Brampton Valley Way through the Kelmarsh Tunnels in Northamptonshire is predominantly flat and well-surfaced (tarmac or compacted gravel), as it follows an old railway line. This makes it highly accessible for walkers of all abilities, cyclists, pushchairs, and wheelchairs on the main path. The tunnels themselves have a solid, often concrete or brick, surface but are completely dark and can be damp underfoot, with puddles after rain. The path between the tunnels is also flat and surfaced. This Northamptonshire trail offers good underfoot conditions outside the tunnels.

Dog Notes:

The Brampton Valley Way, including the Kelmarsh Tunnels section in Northamptonshire, is very suitable and popular for dog walking. The wide, flat paths are comfortable for dogs. It is generally advisable to keep dogs on a lead or under close control, especially as it's a shared-use path popular with cyclists and can be busy at times. Some dogs may be nervous or disorientated in the completely dark tunnels, so be prepared for this and keep them close. Please clean up after your dog; bins may be available at main access points or car parks along this Northamptonshire trail.
