Along the way, you’ll cross ancient paths, rolling coastlines, wild moorland and peaceful villages as you tick off a truly iconic ultra-distance.

That’s why this route is waymarked, fully supported, and set at a pace that allows everyone to take part. There are no strict cut-offs. No pressure. Just a commitment to get you to the finish line, whatever your pace.

Exceptionally clean shower block and very helpful friendly staff.
Excellent staff. Very welcoming! They keep a very close eye on all aspects of the park and take immediate action to attend to any problems which arise.
Even in October for our last stay we found the park to be in superb condition. A great tribute to the hard working park staff which was much appreciated. We look forward to returning.
The staff are always very friendly and go out of their way to help. My daughter loves Warren Mill and is always in the park playing before we start setting things up. It’s a lovely friendly site that I often recommend to people I know.
We hired your BBQ hut and what a fab idea it was! Kids loved it, it was a fab little experience.
Overall, we really enjoy staying at the park and find it very friendly and well maintained.
A really great park, fab shower and amenity block. We are new to the motorhome scene and this site has strengthened our commitment to our new freedom Thank you for a great site!!!
We absolutely love this place and will definitely return.
Excellent park, easy to get to, will definitely recommend to friends and family and will return in the future.
Our daughter loves coming to Warren mill and has great fun. The staff are always helpful and friendly and we’ve made lots of great memories and look forward to making lots more soon.
Thank-you very much for an enjoyable stay. It has been my favourite camping trip. I loved the adult only camp area. Highly recommended to friends.
Nice park in an excellent location for touring Northumberland. Good facilities and friendly staff.
