One of the tougher sections that may require a dismount.

Chumash/Las Llajas trail
May 24, 2019 near Santa S…, CA
The first big rock climb section on the way up Chumash Trail. (There's a few short rubble piles before this, but this is where the real fun of this trail begins). This section is rough and off-camber, but the rock is grippy and solid, so it's rideable : )

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 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 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.
Nov 15, 2022 near Santa S…, CA
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.

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)
