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 winding side road is very lightly trafficked and carries you between Stanford and the Palo Alto hills with partial shade the entire way. On the east side of the road you will find Frenchman's Tower, and old brick landmark.

Page Mill Road is a classic route for cyclists looking for a challenge, with its steep climbs, sharp switchbacks, and stunning views of Silicon Valley. Starting near Palo Alto and climbing into the Santa Cruz Mountains, the ride tests your legs but rewards you with breathtaking scenery. Be prepared for varying gradients, especially in the lower sections, and pack plenty of water—the climb can be intense, especially on warmer days.

While this is an expressway, there is good room for safe riding and most of the day it isn't too heavily trafficked which makes for a great, rolling straight run
