Running the East Bay Wilderness

San Francisco Las Trampas Regional Wilderness

Added by The Outbound Collective

  • 4.5-mile loop run touring this east bay ridge
  • 900 feet of elevation change to keep the lungs burning
  • Push yourself through the challenging mud puddles and open grassy spaces
  • Duration: 2 hours

Take time to stop in the first area, Rocky Ridge with it’s grassy knolls to enjoy views in all areas. Head up the Eldeberry Trail, which will take you up the muddy or sunny (depending on the time of year) side of the ridge. Once you’ve made it through the mud, the trail returns to grassier open space for your enjoyment. Just short of 2-miles, you’ll come across Upper Trail, which you’ll start taking up the hill to the top of the ridge. Be sure to enjoy views from the top point. At 2.25 miles, you reach Devil’s Hole. This is where you can choose to head back or if you’re up for it, drop down the west side of Rocky Ridge for another 2.5 miles to take you back to the original trail. On the route back, instead of taking Upper Trail, head on Cuesta to enjoy trails which angle along the hills. Plus, to stay on the less busy side, Cuesta is only open to hikers and equestrians.

Cuesta ends at a junction just over 4-miles. From here, head right on Rocky Ridge, to take you back to the gate.

To reward yourself for this trek, head to Pete’s Brass Rail to take in some homemade Mexican food or beers.

Sunday afternoon dog-friendly adventure

I love Trampas! So peaceful and beautiful, can't believe it's so close to home too. I had never done this side of Trampas, so I followed this route. Really liked it, but would recommend dropping into Devil's Hole or staying on the Ridge Trail for better views. Cuesta was meh.
