From the Rancho San Vicente entrance, pass through the cattle gate and follow the Lisa Killough Trail as it winds up into the hills. This is a popular stretch, and hikers often share the path with cyclists and dog walkers. After half a mile, cross the Almaden-Calero Canal and bear right to stay on the Lisa Killough Trail.

From here, the landscape changes dramatically, alternating between boulder-strewn fields and lush forest. While hiking the open sections of trail, look for sun-loving flowers like the lupine and California poppy. In shadier manzanita groves, hikers can find clusters of bright buttercups. Butterflies and other colorful insects enjoy the flowers too.
