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 hike, 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
. 8/10 of a mile into the hike, you'll reach a junction with a hairpin turn to the right. Take this turn to follow the Buena Vista Catway
as it takes you eastward across the hillside.
The Buena Vista Catway
starts off fairly mellow before suddenly and steeply climbing up the hillside that you're approaching. After 20 or 30 minutes of hiking this ascent, you'll finally top out on a saddle and have a moment to catch your breath. The dirt roadway then transitions into a footpath, which will take you down to the bottom of Buena Vista Canyon via a couple of switchbacks. After crossing the creek, you'll see a junction with the Buena Vista Trail
, which heads to the right (down the canyon). Take this right turn to follow the Buena Vista Trail
The first half of this trail will gradually take you down the canyon's slope before the path flattens out momentarily. The trail then switchbacks down the east wall of the canyon at a steep grade before leveling out as it runs into Park Lane, which marks the end of the Buena Vista Trail
From here, you can turn right on Park Lane to start making your way back to the original trailhead. Follow Park Lane for a little over half of a mile to reach an intersection with Mountain Drive. Turn right here to follow Mountain Drive, and you'll quickly arrive at the trailhead for the San Ysidro Trail
, thus completing the loop.
