Introduction

The Cedar Spring Trail is a well-graded and switchbacked trail that passes through some very interesting habitats, as well as through a number of gates that divide Forest land from private property.
Although the first portion is a road that is fenced on both sides through the private property of the Girl Scout Camp, and a lot of the area has been cleared for fire protection, it is still interesting, and has many of the usual species for this area.
This brief road section ends after one quarter mile after the road crosses the East Canyon branch of Morris Creek. The trail then follows the Creek for the next 0.7 miles in almost constant shade from interior live oak, Quercus chrysolepis. There are thickets of wild rose, Rosa californica, in places, and several patches of velvet ash, Fraxinus velutina, with its very velvety leaves.
The Forest section of the lower trail is grazed, so the plants are seriously munched in areas, and there are fresh cow pads in abundance at times. That portion is followed by a beautiful meadow in the Girl Scout Camp property that has a lot of interesting natives. But there is a quite sharp division in it whose cause is not obvious. The upper meadow is almost entirely a non-native weed patch of mostly Oriental mustard, Sisymbrium orientale.
The habitat changes completely when the trail leaves the Creek and begins zig-zagging up the hot southwest-facing slope of the Desert Divide. This portion has the largest concentration of flannelbush, Fremontodendron californicum, that we have seen at San Jacinto Mountains, accompanied by a large number of hollyleaf cherry, Prunus ilicifolia.
The top of the trail is yet another completely different habitat, where a rare species is found, California penstemon, Penstemon californicus.
This guide is only to the portion of the trail up to the PCT. There is a separate guide to the rest of Cedar Spring Trail, which goes through a completely different habitat on the northeast-facing slopes of the Desert Divide.
Directions to the trailhead. The trailhead is reached via the signed paved Morris Ranch Road, which heads north from SR74 (the Palms to Pines Highway) about four miles west of the intersection of SR74 and SR371, at the fire station just east of mile marker 67.75. It is 3.8 miles along Morris Ranch Road to the Cedar Spring trailhead, just past the Joe Sherman Girl Scout Camp, and 1/4 mile before the end of the road at the Morris Ranch.
There is very little parking at the trailhead itself, only enough for 2-4 cars, depending on whether you can shoehorn your cars into the narrow strips along the road. There is a larger parking area a bit to the south.
Trail length and elevation gain. The portion from the trailhead to the PCT and back is 4.6 miles roundtrip, with 1300 feet of elevation gain and loss. The entire trail from the trailhead to Cedar Spring and back is 6.2 miles roundtrip, with 1700 feet of elevation gain and loss.
The trail starts at 5480 feet elevation, with a fairly uniform and strenuous slope of ~570 feet per mile to its high point at 6780 feet on the Desert Divide 2.3 miles from the start. The trail then descends 0.8 miles to 6400 feet to Cedar Spring (~460 feet per mile), which is the end of the trail.
This guide is the result of just two trips in autumn, on 28 October 2008 and 1 November 2008, and hence is especially incomplete for annuals and some perennials. The definitive determination of many species needs to be checked in spring or summer.

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 131 trails in our database when this histogram was made; 4 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 "4" or smaller may indicate taxa found only in this area of San Jacinto Mountain.
