Wildcat Canyon Loop is a 7.5 mile loop trail located near Cupertino, CA that features beautiful wild flowers. The trail is rated as moderate and primarily used for hiking, walking, and trail running.
Escape the crowds and take in the sights on this loop at the popular park west of Cupertino. Upper Wildcat Canyon is one of the prettiest sections of the park. The trail also climbs to impressive vistas looking out over the South Bay from the Rogue Valley sections of the loop. This route at Rancho San Antonio County Park and Open Space Reserve ventures beyond the popular sections of the park to offer a diverse introduction to the terrain on the eastern side of the Santa Cruz Mountains. Rancho, as the locals call it, draws big crowds with its abundance of flat trails and attractions at Deer Park Farm, but few visitors venture deeper into the wilds of this park seen on this loop hike. Best times to go: Spring wildflowers and winter vistas are the most inviting; autumn will have a touch of fall color; summer will be hot in the exposed areas, but fairly cool in the covered canyons.
This is a pretty easy trail to walk and doesn't take too long. Its a good basic walk for those that don't want a challenging hike. However, the hike is pretty well occupied with people and parking can be a challenge if you don't start early enough, despite "ample" parking available in the area.
Nice work out, and close to Sunnyvale so you can even cycle there, lock your bike at the Deer Hollow Farm, and then hike from there upwards.
