I can’t agree with jitterbug enough. Hiking the AT for me was the best thing ive done in my 20 years and quite possibly might be the best thing i do in my whole life. Everyday was an adventure, a free lifestyle that your completely in charge of. You are surrounded by your friends and beautiful scenary and friendly towns folk-what could be better?
I’ve been done for about 50 days now and im just starting to become “happy” with my old life. I was somewhat depressed after i finished and many things i loved before the AT just didnt do it for me when i was done. I was used to being surrounded by adventurous souls who were out to accomplish the same goal as me. Many of my long time friends seemed dull to me and i didn’t want to spend much time with my group of friends. I felt lost as well as unexcited by almost everything. Coming back to college after a semester off had me feeling out of place and out of the loop. Basically its only time thats made my re-entry better. Not to say i still dont think/dream/read about the AT every minute i can. I’d do anything to still be out there now but its not a realistic option at the time. Weekend hikes on the long trail will have to do. I don’t know if my life will ever be the same again.
To future hikers, don’t be discourged. Don’t not hike the trail because you think it will make your life dull, its just an extraordinary adventure that is hard to top. PCT or another AT hike is definately in my future tho
