Introduction

Beginning at Chinquapin Junction with the PCT in the high country of the San Jacintos, this trail traverses the north face of Tahquitz Peak to reach the Peak. The trail then follows the South Ridge of Tahquitz Peak to the trailhead in Southern Idyllwild.
This guide begins at the top of the trail. The easiest access to that point is to come up this trail from the base of the South Fork Trail; a shadier, cooler way is via the Devils Slide Trail and the PCT.
See also the guide beginning at the base of the trail, which also contains detailed driving directions to get to the lower trailhead.
Highlights of This Trail

The lowermost part of this trail is unique in having some chaparral species present. In his 1902 Flora, Hall describes a big island of chaparral on the southeast slope of this ridge, and attributes it to slope exposure and desert winds, which, gliding over the [Desert Divide] ridge, strike the slope, giving to it a warmer and drier climate than it would otherwise have. The lowermost part of this trail is close to that island, but not within it.
The botanical highlights of this trail are:

Number of Unique Taxa On This Trail

The following histogram gives the number of trails in our database that contain each taxon on this trail. We had 93 trails in our database when this histogram was made; 5 of those trails, including this one, are in this area of San Jacinto Mountain. A number of "1" means the taxon has only been found on this trail among the trails in our database; numbers of "5" or smaller may indicate taxa found only in this area of San Jacinto Mountain.

We found 5 additional species not in the above table, since they have not been identified yet. The unidentified ones are marked with ? or sp in the id? column in the guide, and have no entry in the #all column.
Fieldwork Dates and Summary of List Changes With Time

The following table gives the dates the trail was walked and taxa recorded. After each visit, the table gives the total number of taxa on the list and the breakdown of the taxa without positive identification. See Explanation of Plant Trail Guides to understand the symbols below.

The number of species in the field guide went down on 10/5/04 when some of the unknown species turned out to be the same as ones previously in the guide.
There are two entries for 8/2/06, which was the first date the trail was surveyed beyond Tahquitz Peak. The first entry is for comparison with the previous entries, and records only the section to Tahquitz Peak. The second entry is for the whole trail, but was incomplete for the lower part of the trail due to darkness. The first time the entire trail was surveyed was 8/7/06.
The fieldwork was only to mile 1.79 on 3/10/07 and 5/11/07.
We thank Michael Charters for finding the Sarcodes sanguinea and Stephanomeria virgata on 8/12/06.

Comments On Specific Species

Poa secunda ssp. juncifolia. Plants at mile 0.25 are very different-looking, and as a result formerly were called Poa nevadensis. However, Elizabeth Anne Kellogg showed in 1985 that these different forms are environmentally induced.
Curiously, most vouchers from this area are of ssp. secunda, which is clearly ruled out by every characteristic in the Jepson Manual key. The lemmas are glabrous, not hairy; the ligule of the sterile shoots is only 1 mm and truncate, not greater than 2 mm and acute; and the leaf blade is firm, retaining its shape, not withering after bloom. The non-withering leaves is the easiest trait to observe in the field.
Rhamnus californica. See note in Devils Slide Trail Guide.
Apocynum androsaemifolium. We've never found blooms on these specimens so far. Interestingly, Hall found these same short plants in this location in 1901, and also never observed blooms on them. He did find blooms on specimens in Round Valley on August 13, 1897.
