Trail shared by David Hitchcock

A run through the woods to a creek that flows through the preserve.

David Hitchcock

Features River/Creek · Wildflowers

Los Trancos Preserve is open 1/2 an hour before sunrise to 1/2 an hour after sunset.


The Lost Creek Loop Trail departs the Page Mill Trail and meanders through the woods. It meets up with a small stream that flows through the preserve, especially in the winter and early spring after it has been raining. It's a shaded run and provides you an opportunity for solitude and an escape from the noise along Page Mill Road.

As the trail departs the Page Mill Trail, it climbs steeply through the woods toward the Franciscan Loop Trail at roughly .2 miles. From here, the trail begins to descend toward the creek. It is a dirt trail that is covered in leaves, that makes for easy running toward the creek. The trail begins to descend more steeply through a switchback and brings you to the creek, which you hear before you see it if there is enough water. The creek continues its course downhill and begins to fall below the trail. The trail levels out before making its way around to the right and back toward Page Mill Trail. The creek bed is well below the trail at this point. As the trail rounds the hill, it finally meets back up with the Page Mill Trail. If you go to the left, the Page Mill Trail descends toward Foothills Park but if you go straight, you can follow Page Mill Trail back to the trailhead and then whatever path you need to get back to your car.

It is a nice run through the woods, providing solitude and quiet compared to some of the other trails in the preserve.
