“Run this trail through San Ysidro Canyon to catch a glimpse of San Ysidro Falls while gaining over 3,000ft of elevation.”

As of December 2017, this trail is closed as part of the Thomas Fire Closure. Violating this closure is a federal crime that can result in hefty fines or jail time.
From the trailhead, the San Ysidro Trail parallels a residential driveway for a while before becoming a dirt road. 4/10 of a mile into your run, you'll come across a junction for the Old Pueblo Trail and the McMenemy Trail
1/10 of a mile later. Avoid taking either of these diverging trails and continue straight to follow the San Ysidro Trail. 1.4 miles into the trail, you'll reach San Ysidro Creek, which features a small waterfall and a large pool here.
The trail then continues to climb and after 2 miles of being on trail, you'll cross San Ysidro Creek. Shortly after the creek crossing, there will be a path curving to the right and one that goes straight. Stay on the straight path to continue following the San Ysidro Trail and you'll quickly reach San Ysidro Falls
, which are the highlight of the run. At 60 feet tall, the San Ysidro Falls
make for a stunning sight.
Once you've had your fill of the falls, you'll follow the steep and rugged trail up the canyon wall, utilizing the long switchbacks in place. After 2.5 miles and roughly 1,700 ft. of elevation gain, you'll finally reach the trail's end as it hits East Camino Cielo.
