An arduous climb up Ollason Peak, followed by 10-15 minutes of narrow downhill.

Jordy Boom


See county park web site for hours. Normally 8 am to around sunset. Trails may be closed when rain occurs.
The climb goes up to Ollason Peak at 1800 feet.

It's followed by a descent on the backside of the peak, which then leads into a very narrow singletrack along a canyon wall.

Need to Know

Parking at Toro Park has a fee, though you're allowed to park on the dirt areas outside of the park as long as there is space.

There are 3 small dry creeks (less than 1 foot wide) to cross during the descent that are not optional and require hike-a-bike or jumping.


The trail starts in Toro Park near various picnic grounds, then slowly switches to fire roads and singletrack, leading up to Ollason Peak at 1800'. This is a fairly long and tiring climb.

The reward for the climb is a long technical downhill along a canyon wall. The difficulty comes mostly from the narrowness of the trail, with the canyon lurking below (10-20 feet) and the tight turns.

There are various other trails here that can be combined. After the descent, you can turn left at the main road to repeat the loop.

History & Background

This Pipeline trail was recently constructed, having been completed in 2012.

Getting forecast...

Very impressed with this ride. I survived with my fully rigid single speed. The view on the top is worth the climb. The downhill is likely the narrowest, most twisted trail that I have seen between here and SF. I wish I could lap it. Feb 10, 2016

It's moderately difficult to find the right fire road to the top if you don't have a map or know where to go once you're in the park. Follow the paved road entering the park straight till it ends at a round about. Continue straight on fire road that follows the fence line (don't follow the nature learning trail, it goes up a hill to a water tank). Eventually take a left following the fireroad and signs for Ollason trail. If you miss this left you'll realize it once you enjoy a fast down hill that ends at a gate and have to turn around and climb back out. Great trail! I really enjoyed the wooden obstacles and steep climb sections! Apr 27, 2016

Great for my skill level as I move from beginner to intermediate. Climb is tough to the point where I had to keep doing it in chunks but the downhill was great and challenging. May 30, 2017
