Sequan Truck Trail, Alpine, CA
0:00 – Start of the hike on the Sequan Truck Trail (click thumbnails to see the full sized versions)

This is a hike of contrasts: tall mountains towering above canyons, riparian shade and exposed slopes, suburban and rural. In Alpine, development that has extended east from San Diego meets the rustic landscape of small houses and trailers scattered through valleys in the foothills of the Cuyamaca Mountains and  the smaller local peaks such as Scuyan and Lawson. Mainly using the California Riding & Hiking Trail, this is a reverse hike and since most of the terrain is exposed, plan accordingly, especially on warm days. Much of the trip is on an eastern facing slope, so if you start in the late afternoon, the ridge will block out the sun for a substantial portion of the climb out of the canyon.

0:05 – The dirt road continues through the gate (times are approximate)

Begin by heading uphill and south on the dirt Sequan Truck Trail. At 0.2 miles, pass through a gate and almost immediately, look for the yellow California Riding & Hiking Trail decal stuck to a post on the left side of the road. Follow the trail as it makes a steep descent over loose and sometimes rutted out terrain. Scuyan Peak dominates the landscape directly in front; below, the Sweetwater River cuts its gorge as it makes its way from its Cuyamaca Mountains headwaters to San Diego Bay.

0:07 – Start of the California Riding & Hiking Trail

At 0.7 miles, you meet a dirt service road as it makes a hairpin turn. Continue downhill at a more moderate grade, passing a few rural homes and the remains of an old jalopy (1.4 miles from the start). The trail continues winding its way down into the canyon, finally reaching the river at 2.2 miles. An old bridge crosses the river, but because it is considered unsafe, this is a good turnaround point. You can relax in the shade of several impressive oak trees before making the climb back to your starting point.
