The Spring Valley Area at Ed Levin Park on the east side of San Jose in the Diablo Foothills offers one of the best places in Santa Clara County to observe migratory hummingbirds in spring. Enjoy an easy walk around the Spring Valley Pond and spend some time at the “Magic Tree” watching the hummingbirds come and go, or take the more challenging Spring Valley Trail for a walk in the grassy hills and surrounding woodlands.
