A great find, can’t recommend the park enough to others whether seasoned campers or first timers…
Nice park in an excellent location for touring Northumberland. Good facilities and friendly staff.
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!!!
Having previously mainly stayed at Parkdean Caravan Parks on the south coast I was unsure what to expect, we were delighted with the caravan we stayed in, much better than previous holidays, so clean and spacious, and a great price. Really felt comfortable and safe, which as a single mum of 11 and 13 year old lads is always my concern, so thank you very much for a perfect holiday.
We very much enjoyed the campsite. The kitchen area for wigwam users was a great touch and made a huge difference to our dining options. All public areas well maintained and clean.
Excellent park, easy to get to, will definitely recommend to friends and family and will return in the future.
We have travelled all over the UK in our motor home. Waren Mill was one of the first sites we stayed at and has remained our favourite!
We absolutely love this place and will definitely return.
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.
Superb place and facility. I’ve never been to Northumberland, and now will be returning back for the third time in 9 months (even though you are 360 miles away from me).
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.
Loved our holiday here. Was pretty much perfect for us with small children. Have already booked to return twice in the summer.
