Enid Pearson-Arastradero Preserve offers rolling grasslands mixed with oak and evergreen trees. The trail system starts on pavement and transitions to packed dirt and gravel—great for bikes with wider tires or a solid gravel setup. Keep an eye out for deer, coyotes, and even bobcats, and take a moment to pause at one of the benches or by Arastradero Lake to enjoy the open views.

The Northern part of Alpine Road is a paved and curvy descent through wooded areas and runs parallel to Coal Mine Ridge Preserve, eventually connecting with the trailhead there.

This mostly paved bike trail alongside Alpine Road is great for bike commuting — just don't run over any slower trail users! The trail runs all the way from Portola Valley to Stanford, offering some nice shade along the way. The brief moments of unpaved trail are near the Portola Valley end.

This fantastic tavern, founded in 1852, is the second oldest in the state. It features a large, beer garden-style outdoor area with plenty of shade. An extensive beer and food menu makes it a perfect stop to enjoy a brew and some great food after a ride.

Boronda Lake features a couple scenic picnic areas with piers out over the water. A small arched bridge leads out to Sunfish Island from a trail on the side of the lake opposite the road. This is great place from which to enjoy beautiful Foothills Nature Preserve.
