This is a great 7-mile loop with easy access to water. This trail includes big hills, rolling hills, flats and downhills. There are lots of dense redwood forest that make it a great choice for a relatively cool run on a hot day. In the winter, enjoy the lush ferns under the redwood canopy.

Need to Know

This loop is mostly shady. Water can be found at the start at the Richard C. Trudeau Conference Center and where the Graham and West Ridge trails intersect.

Runner Notes

Lots of roots on on the French Trail.


Park at the Trudeau Center parking lot off of Skyline Blvd. Follow the Dunn Trail, which starts behind the Trudeau Conference Center. You immediately pass Sargent Cypress trees on your left, a California endemic tree with a relatively small distribution.

You then head uphill through the another unique California habitat, Serpentine Prairie. You can stop to read abut this ecosystem on an informational placard. Continue up the Dunn Trail to the Graham Trail, and turn left. Run on the Graham Trail for just over 1 mile; this section is mostly uphill and on a fire road. You'll arrive in an large open area called Redwood Bowl. There is a water fountain here.

Next, take a sharp right onto the West Ridge Trail. After .1 mile, take the first trail that breaks off on the left. This is the Madrone Trail. Take this singletrack trail .5 miles to the French Trail. Take a right on French Trail and run for 2.5 miles. You are traveling along a steep hillside under a redwood canopy on a very unique trail in the East Bay. This trail ends at a junction with the Orchard Trail.

Take a right and head uphill for .2 miles to West Ridge. Take a right on West Ridge, and continue .3 miles to the Baccharis Trail. Take a left onto Baccharis Trail. After .5 miles, this trail will take you back to Dunn Trail. Bear left onto the Dunn Trail. After .85 miles running through a beautiful live oak canopy that is the quintessential coastal California habitat, you'll return to the intersection of the Dunn and Graham Trail. Hang a left here and take the Dunn Trail back to the parking lot where you started.

Flora & Fauna

In addition to a great forest of coastal redwoods, the park's 1,830 acres also contain other evergreens, chaparral, and grasslands. Wildlife within the park includes rare species such as the golden eagle and Alameda striped racer. Deer, raccoons, rabbits, and squirrels are often seen.

History & Background

The forest's peaceful groves give little evidence of the park's bustling past–in the mid-1800s the area was the scene of extensive logging to supply building materials for the city of San Francisco. The logging era has long since passed, and a stately forest of 150-foot coast redwoods (Sequoia sempervirens) has replaced those that were cut down. There was one particularly giant tree in this forest that was used by 49'ers as a navigational guide through the Golden Gate before it was cut down during the logging era.
