Sunol Regional Wilderness Hike


Sunol Wilderness Dog-Friendly Hike

Sunday, October 31

Sunol, 11:00 am







This is a beautiful large park in the East Bay. We will hike to the top of Flag Hill.  This hike requires a reasonable level of fitness. It is less than 4 miles long, but with a 1000 ft elevation gain.  On the way down, there are several options so you can make it a 5 or even a 9 mile hike if desired. Sunol park not only allows dogs but they can be off leash once outside the more crowded park area. As we will be in a group, of course your dog needs to be dog- and people-friendly.


What to bring:

  • Sturdy hiking / walking shoes
  • Water
  • Lunch, trail snacks, fruit
  • Hiking poles (optional)
  • Layered clothing: you’ll get warm hiking up, but depending on the weather, coming down can be chilly.
  • There are toilets and drinking water at the trailhead, but not at the top. There is a small entrance fee for parking ($5) and for your dog ($2).



Sunol Regional Wilderness: Sunol East Bay Parks




From the East Bay: go south on 680. From San Jose: go north on 680:

Take Calaveras Rd exit (close to the Livermore or Sunol exits)

Turn right onto Calaveras coming from the south, turn left coming from the north.

After 4 miles, turn left on Pat Geary Road. The park entrance is another 1.8 miles.


We’ll get together at the bathrooms, close to the small bridge at the trailhead to Hayfield Trail. Cell phone coverage is very spotty in the park so please get there on time as we won’t be able to wait long.
