England: Coast to Coast Trail

This, I must say, is one of my favorite trails.  It extends 190 miles from (Irish) Sea to shining (North) Sea, has plenty of relatively inexpensive lodging options and food supplies, and is saturated with enough sources for literary references to keep an English Literature major justified in her selection (hullo, Wordsworth and Wuthering Heights!). The "Coast to Coast Walk" was devised by Alfred Wainwright, a British walker.  It stretches from St Bees Head on the west coast to Robin Hood's Bay on the east, passing through the Lake District, Yorkshire Dales, and North York Moors.
