A scenic stop just off the winding roads of the Santa Cruz Mountains, Lexington Reservoir County Park is a great spot to catch your breath and enjoy the view. The smooth pavement along Alma Bridge Road makes it a popular stretch for cyclists, with rolling terrain and minimal traffic. There's parking, restrooms, and shaded areas if you need a break. From here, you can loop toward Los Gatos or push deeper into the climbs of Highway 17 and Old Santa Cruz Highway.

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.

Guadalupe Creek flows eastward from San Bruno Mountain in San Mateo County, passing through San Bruno Mountain State and County Park and Brisbane before reaching Brisbane Lagoon, a remnant of San Francisco Bay. The area is home to endangered butterflies and the San Francisco garter snake. The creek can be seen from Hicks Road, and it winds along the side of the road.
