The Pacific Crest Trail is a 2,663 mile long trail reaching from the Canadian border in northern border in Washington, through Oregon, to the Mexico border in southern California. Hiking this trail can take 4-6 months and it purposefully avoids civilization. The Cascade and Sierra Nevada mountains make for both difficult hiking and beautiful unspoiled scenery.
After a trying few years after the death of her mother, author Cheryl Strayed started her PCT trail hike despite her outdoor inexperience. Her book, Wild: From Lost to Found on the Pacific Crest Trail chronicling her hike came out this past spring and was well reviewed. I promptly put this book on my to-read list as doing a long hike lingers at the bottom of my life to-do list.
