Squiffy
Warkworth might be worth checking out. It is small, has the River Coquet running on three sides, has a ruined castle and isn’t far from the sea. There are no supermarkets or big stores, which may be a disadvantage unless you do online shopping.
It floods really badly though. Nearby Amble is a very up and coming area I think, though. And Newbiggin by the Sea is very up and coming and great for dolphin watching. It has a very active dolphin watching group.
