  • We enjoyed this tour! They kept the group small. The park service guide was enthusiastic, animated, and knowledgeable. Good signs and photographs helped tell the story.

  • Decently marked and maintained trails. Ample parking with multiple lots. Views are pretty good, stretching from the delta to the north and Mt. Diablo to the southwest. Nice rolling hills with sporadic foliage. Some parts shaded but mostly exposed. Great for spring/winter hikes, during which you may catch flower blooms.
  • Beautiful green rolling hills during springtime. Literally a Microsoft wallpaper, but in real life! Kiosk was closed when I visited, according to website they’re “seasonally open” so not sure when they start collecting fees. Took advantage of that fact and we enjoyed an amazing hike with views of Mt Diablo, the delta, and surrounding hills. Beautiful wildflowers everywhere! Dog friendly as well, our dogs enjoyed the hike off leash.
