Overview

This is go to after work ride if you are looking for a steady uphill fire road climb followed by a very rewarding fast flowy downhill. It's not terribly technical on the downhill, but there are a few sections that the less experienced rides may have to dismount on.

Description

From the Las Llajas trailhead, on Evening Sky Drive, follow the fireroad by taking a right hand turn at both forks you'll encounter. Once you reach the top of the fireroad you'll continue downhill for about 3/4 of a mile and encounter a short climb that takes you to the Chumash Trail located on the right. The Chumash trailhead is marked by a wooden sign. Here's where the hard work is left behind and the fun begins.

Head down the fast and flowy, mildely technical in spots, singletrack until the trail starts to widen at the very end. You want to take the singletrack to the gate which will dump you out onto Evening Sky Drive. Once there follow the road back to the Las Llajas trailhead. If you happened to miss the singletrack you'll arrive at the Chumash Trail, just turn around and look for the singletrack to the left and you'll be headed the right way.

One of the tougher sections that may require a dismount.

Looking up the last rock wall before the junction at Rocky Peak Trail (which you can see in the upper left). One of the hardest sections to clean, and a good challenge coming back down, too.

Looking up into the last couple hundred yards before the junction with Rocky Peak Trail. This last stretch offers half a dozen small rocky sections, a couple are deceptively tricky. Good challenge, great fun!

Looking up the last sustained rock climb section before the top of Chumash. It's rideable but very challenging. At the bottom, try hugging the right edge up over the rock mound, which gives you a split second of momentum before charging the main grade.
