Craster nice for a decent pint and some pub food, walk to a castle. Buy some kippers. As is alnmouth minus the kippers.
Alnwick castle/ gardens is nice as well, barter books in Alnwick is worth a look.
Lovely coastal walks pretty much anywhere along the coast.
Don’t bother with seahouses.
The little pub at low newton by the sea is worth a visit at the end of a coast walk.
Harthope valley, Ingram valley are nice for picnics on the east side of the cheviots. The old road to chew green is worth a trip if it’s open.
Lindisfarne is great but always better to stay if the tides coming up and everyone else leaves. We have a campervan and just to sit in the car park, watch everyone hurry off and then watch the delivery vans hurry over and hurry back and wait for the wildlife to come out is amazing. Watching kestrels and owls hunting in the car ok field margins and waders galore turning up is amazing. The place is transformed.
There’s a really nice round the island walk which is well worth a couple,of hrs with a bit of exploring and beachcombing. Don’t know what pubs best at the moment. The ship in the main st is a bit old fashioned and disappointing. The crown and anchor looks better these days.
Cragside nt is worth a visit and the stuff for kids and the drive is good, as is the house and cafe etc but closed now. Wellington nt is a good alternative not too far away and on the way from kielder to the coast.
The barn at beal on the ridge before you drop down into the lindisfarne causeway is good for coffee/ food.
Lots of stuff to see, walk, picnic, eat etc. Some good galleries around even in the smaller towns. Good art gallery in wooler as well as the best women’s only running/ walking/ fitness gear supplier. If only they did men’s clothes, great selection of really top notch niche brands.
