A quick, uncrowded, mostly shaded, feels like you are in the wilderness and has wonderful views, loop. We often say to each other "I can't believe this is in our back yard"!

There is plenty of climbing, but there are many fast flowy turns, too. It is just as much fun to go slow and enjoy the company and the environment as it is to race through the Madrone Trail - Las Trampas Regional Park at top speed.

Need to Know

The East Bay Regional Park District plows the fire roads in June or July every year. Depending on the touch of the person doing the plowing, the trail could be very dusty and slippery for a month or so. Also, the trails are too muddy to ride after several winter storms in a row.


This loop can be done in either direction. Going counter-clockwise has the advantage of gaining most of the elevation on pavement and having more downhill to ride on the Madrone. The disadvantage is that you have to climb "The Elevator", a short but steep grade just after entering the dirt.

  • Start at Alamo Starbucks/Ace Hardware parking lot and proceed up Las Trampas Road.
  • At about 1.25 miles you'll run into a gate for a gated community. Go around the gate, the EBRPD has an easement for hikers and bikers to use the private road to access the park.
  • At about 1.75 miles take the first right (there is a small EBRPD sign) and go about 100 ft to get to the dirt access road.
  • Proceed onto the fire road. After a steep downhill there is a very steep uphill (we call it "The Elevator").
  • Continue climbing, pass another gate (the actual entrance to the park), continue climbing until you tee into the Madrone trail.
  • Go left to follow the Madrone.
  • The Madrone weaves in and out of ridges and canyons at about 1000ft elevation. Most of the trail is in shade but when the trees go away the views are great to the East.
  • There is a really nice grove of Madrone trees at about 4 miles.
  • At about 4.5 miles there is a fire road down to South Ave. There is no legal exit for bikes from this road. Continue straight for another mile or so and take the next left on the Camille Ave Access to Las Trampas Regional Park
  • Exit on Camille Ave
  • Take the Iron Horse Trail back to the start

Beautiful ride with oak trees and doubletrack fire road. A lot of paved road biking on this loop but good cardio. Madrone is a fun up and down. 7.8mi — 1h 14m

Did the route clockwise today for the first time - it was slightly less difficult than counter-clockwise. No "elevator," which zaps a lot of energy.

This loop fits my personal definition of the worst type of MTB trail - really steep climb (in spots) on a fireroad followed by steep, no-fun descent.

It was my first time here. Didn't do the full loop and I went the wrong way at first trying to find the trail so I had a few extra unintended miles. 8.2mi — 1h 20m
