Some Mud - Some mud spots here and there and some puddles. The sand is wet and compact right now so it makes for really smooth riding! History

Getting forecast...

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

Features -none-

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.

Difficult Difficult

Great warm up climb. I had to granny gear it near the top due to loose dirt and steep grade. The pipeline descent is well built. One annoying factor was low hanging trees to duck under. Go slow your first time, as it's difficult to know what's around the corner. Nov 17, 2017
First time in this park. Easy climb half way then harder to the Ollason Peak. Wanted to do the pipeline loop but there is not such a trail on the map. Was getting late. Decided to go back halfway and took another trail from the map. Hopefully they will mark that loop on the next map. Otherwise it was a nice ride and that Park have several challenging trails. Definitely will go back. May 31, 2018
Climb is long but isn't bad. Pretty views. Steep in some spots but never too steep to ride after a break. I wouldn't rate the way down as super technical. Nothing is worse than the first drop into it. It's quite fun and well worth the climb. Very pretty. Definitely going back and all the places I had to pause because I didn't know what was around the corner I'll ride through now. I'm only in Monterey a couple times a year (home town) and normally ride in San Diego, but this will be the first trail I will always do coming back now.… Jul 9, 2018
