Trailheads in the Sierra Nevada
There are several hundred identified trailheads in the publication. These are the spots where trips typically originate from or end at. In selecting trips, one can choose to look only at trips originating from (or ending at) a selected trailhead.
After a trailhead is selected, information is presented as to (1) where one gets permits for travel from that trailhead; (2) restricted periods and quota information; and (3) driving instructions. The quota information (when available) can be quite useful in suggesting usage of a particular trail. After this information is displayed (the information is printed when a trip is selected), one can initiate a walk starting from that trailhead.
