Have a 'Google' at South Meadows Caravan and Tenting Park. Privately owned, but extremely well run. 15 Miles north of Alnwick / 15 Miles south of Berwick. 1 Mile off the A1 - no noise problems. 6 Miles inland from Bamborough. Great for walking. Village (Belford) 10 minute stroll away. Golf club about 2 minutes away, non-members welcome.
If you are in the Caravan Club there is a lovely site on the edge of River Breamish or even a site at Durham.
Hope this helps.
