The most difficult part was adjusting to a trail with few reliable water sources. Clear cold water is abundant in the high Sierras, but south of Cottonwood Pass, water sources quickly increase up to 40 miles apart. Carrying 2-5 liters of water takes some getting used to, as does being dirty all the time. (There are few swimming opportunities.) Once south of Tehachapi the trail begins to pass through more populated areas, so resupply and support becomes more frequent, offsetting much of the difficulties with the lack of water. Showers, laundry, cold drinks and food are more accessible. Unfortunately there were several trail closures due to fires and an endangered frog, so some road walking and/or hitching was necessary.
