The Portola Road – Old La Honda Road loop is a classic road cycling route that takes you through some of the Bay Area's most picturesque landscapes. You'll start with a gentle roll on Portola Road before tackling the renowned Old La Honda Road climb, a sustained ascent through oak woodlands that gradually gives way to tranquil redwood groves. This 9.1-mile (14.7 km) loop, with 838 feet (255 metres) of elevation gain, offers a rewarding challenge for cyclists, despite its overall easy rating, and can be completed in about 46 minutes.
Planning your ride is straightforward, as the route is well-known and easily accessible from Portola Valley. While the climb up Old La Honda Road is a highlight, its narrow, twisty nature means descending it is generally discouraged; many cyclists opt for alternative routes like Highway 84. Parking can be found in Portola Valley, though it's wise to arrive early on busy days to ensure a spot. The consistent grade and shaded sections of the climb make it enjoyable even during warmer periods.

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.

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.
