Summary:
I used to ride this trail before work when I worked in Pasadena. It's a great ride in the mornings before the sun is at its strongest. Riding the climb when its sunny is a real killer (bring plenty of water).

Recommended Route:
Climb up to the first junction, turn right then look for the el prieto trail back down

Other recommended trails in the same area:
el prieto, lower arroyo seco

Summary:
This ride is one of LA's best. It is "freeway close" to just about anyone with the trailhead just 1 mile north of I210 near Pasadena's NASA/Jet Propulsion Laboratory. While only about 16 miles long, this loop's demanding climbs and incredible singletrack gives this ride a feel of epic proportions. The variation in trail terrain and vegetation is remarkable as the trail switches from sun-drenched ridgeline to cool, shady, tight-canyon streambeds. The views of the southwestern Angeles National Forest are almost too much to endure during the very technically challenging and tight Ken Burton singletrack downhill.

Distance: 15.5 miles
Elevation Gain / Loss: 2,600 gain
Aerobic Difficulty: Strenuous
Technical Difficulty: Non-Technical for most of route. Ken Burton Trail and Gabrielino. Trail have short sections that are extremely technical to unrideable.
Trail Type(s): Approximately 30% singletrack, 10% paved, 60% fire road

Recommended Route:
Take the I 210 Freeway towards Pasadena to the Arroyo/Windsor Exit. Travel north from the exit off ramp on Windsor Avenue for about 1 mile. There is an unsigned parking area to the left, just northwest of the intersection of Windsor Ave . and Mountain View Street, just before the road takes a sharp turn to the right. Park in this parking lot. Ride your bike to the by going north of the parking lot where three paved roads intersect, and take the middle road around the gate .

Other recommended trails in the same area:
El Prieto, Garbrielino, Sunset, Epper-Middle-Lower Sam Merril, Mount Lowe.

Summary:
This is a good short workout trail with a few options coming down. Start of with pave and after a mile choose to go up toward right side and continue to climb for another 3 miles and reach the saddle. you can turn around and come back down or keep going toward Ken Burton saddle another 3 miles. Or do the El Preito check out the review on that.

The climb is not too steep but it just keep going average 8-12 percent, coming down however, be careful there are quite a few off camber turn and loose sand.
