Tunitas Creek is the most scenic and epic bike climb in San Mateo County.  The climb takes us through a gulch following Tunitas Creek much of the way.  We highly recommend this spectacular bike climb.

Views along the climb.

The road is windy, narrow, and one-lane but in good shape.

The below Climb Report is by Mike Persellin of Minneapolis, MN:

Tunitas Creek Road is hands down the most beautiful climb on the west side of the Santa Cruz Mountains.  From Half Moon Bay, Tunitas Creek Road is 8.2 miles south on Highway. 1.  Santa Cruz is 49 miles to the south.  The base of the climb is two miles from the junction of Highway 1 and Tunitas Creek Road -- not much climbing before that.  The start is on the treeless dunes that run all the way down the coast.  In just a few minutes, the road enters a tunnel of redwoods -- you won’t see much sun until the top, 5.8 miles beyond.  There is little to no habitation, and no traffic.  It is eerily quiet.  The road is above the deep cut of the creek and giant trees fill the entire valley.  The steepest section is a third of the way up and is 1.2 miles at 9.4%.  The top is at the intersection with Skyline Boulevard.  This is a gorgeous climb and not to be missed.

Tunitas Creek is often done in tandem with Old La Honda Road.  To do this, go straight across Skyline Boulevard and you are at the top of the 5-mile descent of Kings Mountain Road.  At the bottom, take a left on Woodside Road and ride 1.1 mile to Woodside.  Take an immediate right at the market onto Mountain Home Road.  From there it is 2.8 miles to Portola Road, where you’ll then ride and 0.5 mile to Old La Honda Road and the start of the climb.

The climb ends at the junction of Tunitas Creek Road and Skyline Boulevard (Highway 35).
