Mostly Dry: Water in the creek below the dam, but not above. Lowest switchbacks need repair still. History

Getting forecast...

A moderate loop and popular option out of Altadena.

Features -none-


This approximately fourteen-mile loop can be done after work or with minimal driving. The ride is made up of a fire road and single/doubletrack climb followed by a singletrack downhill and an easy cruise back down the Gabrielino Trail.


Start at the parking lot on Windsor and Ventura in Altadena. Head north on Gabrieleno Trail - paved turn right at the fork and continue up Fern Truck Trail to the saddle, then make a left at Brown Mountain.

Continue on Brown Mountain until it ends, then go straight onto the Ken Burton Trail. Continue on Ken Burton Trail until it ends and intersects with the Gabrielino Trail. Make a left and cruise the remaining four miles back to the parking lot. Watch out for hikers, especially on the Gabrielino Trail.

History & Background

Ken Burton Trail is an old trail built by mountain bikers that has been closed for years and has just re-opened making this loop possible again.

Inspecting recent trailwork by MWBA volunteers. They did good, lots of brushing on upper portion and some needed tread repair near the memorial. 15.6mi — 2h 28m

The trail closure on the Gabrileno is now north from where the Ken Burton meets it, all the way to Switzer's Falls. There's a big wash-out on the stretch of the Gabe between KB and where it descends into the washbed, proceed with caution. Once you're in the washbed the trail is flagged pink but the course will probably change each time it rains. After 1/4mi the Gabe exits the wash on the right. Jul 16, 2017
Very sketchy descent. Ton of tight switchbacks and loose gravel. Not fun unless your Danny MacAskill or enjoy carrying your bike. Better of turning around and coming back the way you came when you reach the top (around 7.5 miles from carpark). Mar 26, 2018

A fun trail with a backcountry feel when you descend and hit the Arroyo Seco wash bellow. I've tackled it at night a few times before and man is it cool, wouldn't recommend it to new riders of the sport due to it's scissor like switchbacks in some areas but with a little balancing you can clear everything fairly easily. Be cautious after heavy rains because the Arroyo Seco can sweep you away or force you to climb back up where you came from. Beware of the bottom section that's giving away into the Arroyo, a fall from there will put you in the hospital or in a grave. This trail is best enjoyed with a small group of experienced riders and fresh beers in the parking lot afterwards. Apr 14, 2018
