Sunol Wilderness

- Several day hikes in the Sunol Wilderness.


  • Bring lots of water! Typically I bring two liters in my Camelbak (or two liters for me and Pepper). I have seen a water jug put out at the trailhead, but I don't think there is drinkable water there in general.
  • Wear comfortable trail shoes (like tennis shoes/ sneakers). Trails are nice but are in varied condition.
  • If you start in the morning, bring layers. It can be chilly and foggy to start and then burn off into very warm sun.
  • There can be many small trails that split off a main trail, so just be careful you are heading the way you want to go and have a good map.
  • Be prepared to see cows. They can be near or on the trail.

  • Steep climb up to the peak of Flag Hill with a broad, spectacular summit.
  • Lush green hills with plenty of wildflowers.
  • Cave rocks along Indian Joe Creek were very cool.
  • So many cows! Stopped by them at one point heading back to the trailhead.

Hike 1 Highlights

  • Long, rolling hike through the hills towards Ohlone Wilderness. Lots of interesting features, hills and views.
  • Very green with off and on showers.
  • Didn't see many people, other than near the trailhead, just a lot of cows.
  • Trails were not well signed.


  • Location: Hike towards Goat Rock and backpacking camp sites, Sunol Regional Wilderness.
  • Date: January 2022.
  • Stats: 8 total mileage with 2,400+ ft elevation gain
  • Why I chose this trip: I had seen that the Ohlone Wilderness trail made its way from Lake Del Valle to Mission Peak and the route was dog friendly. The Sunol trailhead was closer, so I figured I would explore. I had a goal of heading as close to Mt Rose, the highpoint, as possible. Super fun!
