Overview

This is a combination of arguably the two best trails in Simi Valley. This ride has a mixed bag of goodies to delight any rider.

Description

From the Chumash trailhead, start the 2.5-mile climb up the singletrack Chumash Trail until it ends at the Rocky Peak Road. Along the way, you'll encounter many tricky technical sections (loose rocks, boulders, a few tight switchbacks), that will surely challenge a wide range of riders.

At the top of Chumash, take a right on the fire road (it's technically a fire road but it has a lot of technical sections not normally associated with fire roads) and blast it to the Hummingbird trailhead.

The Hummingbird trail packs a mixed bag of terrain. Loose rocks, large boulders, a 8-10' roller drop, tight switchbacks, high-speed sections, and a few small jumps.

The end of the trail dumps you out into the Hummingbird parking lot. From here, you'll see a white fence across the street, go through the fence and follow the fire road until you see the culvert. Follow it until it turns into singletrack (Hummingbird) that heads towards a water tower. Follow the singletrack and it will take you back to the Chumash trailhead.

Hummingbird DH - Simi Valley, CA
Nov 8, 2018 near Chatsworth, CA
One of the tougher sections that may require a dismount.

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.

Looking back down Chumash from the junction with Rocky Peak Trail (crossing in the foreground). A perfect cross-country / down-country descent with technical rocky outcroppings and smooth but often narrow singletrack all the way to the bottom.

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!

Morning light creeping into the ravine of lower Chumash Trail. One of the best combinations of singletrack + technical climbs + rocky descents in the region. Far less gnarly and consequential than the full DH descents (Grudge, Undertow, and Hummingbird)
