Looking for a good adventure memoir!

Adventures are my favorite subject to read about and I'm looking for my next book! Topics of interest include memoirs about hiking, camping, train travel, travel in general, National Parks. Ideally set in the U.S. but I'm open minded. Also ideally with female lead(s), though I don't want anything too focused on the fact that she's a woman…just her experience! More than one main character is a bonus. A book I really like was "Almost Somewhere."
