Buses run between Newcastle and Alnwick.
Alnwick has no train station, but it is possible to take the train to Alnmouth and catch a taxi or a bus to Alnwick (less than 5 miles).
Alnwick is home to Barter Books, the largest second hand bookstore in the UK, housed in the former railway station. It is the loveliest place and its charm is complete with its own small fireplace, old Victorian sofas and even a miniature train running on top of the bookshelves. It holds some very old and rare books and even has its own cafe in the back.
A good cheap (especially by UK standards) pizza place is in the high street.
The Hairy Lemon is quiet, well-priced public house in Bondgate Within, located halfway between the Castle and the Market Place
Blackmore's is a friendly new modern bar next to Alnwick Playhouse, Bondgate Without. Much more friendly atmosphere for tourists.
