This is the guide to the portion of the Cedar Spring Trail from the Pacific Crest Trail (PCT) to Cedar Spring itself. For an introduction to this trail, direction to the trailhead, and the length and elevation gain of this trail, see Cedar Spring Trail: Trailhead to PCT.

This guide is the result of a single trip on 28 October 2008 and hence is especially incomplete for annuals and some perennials. The definitive determination of many species needs to be checked, since the initial survey concentrated just on finding the species here.
