I live in Alnwick I can be on the coast with 5 minutes drive and Kielder takes about an hour, big Northumberland may be but with the exception of bank holidays the roads are usually prett good.
Fancy something quirky?

Seahouses is well Ermmm! A bit touristy it makes its money from the static caravan parks. Good chip shops and the Puffin cruises but other than that it has nothing much more to offer.
Bamburgh has some descent little food places, The Joiners Arms High Newton, The Ship Low Newton should be quitish in June. Warkwoth for Bertram’s and Cabose then along the road to Morwick Ice Cream.
Craster for the Kippers there is no argument they are the best and while there The Jolly Fisherman
Alnwick has the castle, gardens Barter Books and a small steam railway project that’s starting to take shape. Food wise there’s The Pantry, Yan’s Chinese which is very good, The Dirty Bottles Smokehouse that does good food, beer and cocktails, there’s The Tavern Steakhouse but I’ve not tried it yet as its just reopened. Also a cheap Italin’s opposite the Playhouse.
Amble is worth a visit now it’s really being revamped along the harbour with little pop up shops and a cracking Ice Cream parlour. There’s Zecca at the top end that does good seafood, pizzas and steaks.
