This mostly paved bike trail alongside Alpine Road is great for bike commuting β 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.

3 miles of great winding mountain road. It ascends from the Palo Alto side up to the Skyline road. Quite narrow in places and fairly steep, but only light car use means this is a fun road climb.
