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

First time. Very loose and sketchy on the switchbacks. Convenient arrow made of rocks to path off the arroyo. Some fun flowy sections. 14.7mi — 2h 46m

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

I have to agree with Naterzz, the descent on the back side is very sketchy indeed right now. The brush is grown over in multiple places and there were a couple spots where the trail was completely washed out and you are 1 slip from sliding off the edge of a steep drop. Once you get to the bottom, you ride through the sandy gravel of the washbed trying to figure out where the trail picks back up. I just kept pushing forward and found it without much trouble. You are then on fairly flowy trail most of the way back, although you cross the stream a good 7-8 times. It water was flowing today and I definitely got a little wet, but it was warm so the crossings were pretty fun. I definitely wouldn't recommend this ride for new riders. Oct 19, 2018
Highly recommended, and definitely a moderate loop compared to the typical San Gabe ride. Less physical than Chantry Flat, not dangerous like the Wilson Trail, technically easier than the Mt. Lowe shuttle. The main climb is under 2000’, only really steep for a couple minutes. The Burton descent is technically challenging in the switchback zones, otherwise connected by long smooth runs. The exposed sidehilling so common to these mountains is mostly buffered by dense growth that would stop anybody from tumbling far. That said; a few obvious places do demand extreme caution. Once down in the creek things unfold fast and flowy, with currently zero navigational confusion nor any soft sand. The section of most concern is the short ride-around halfway down Arroyo Seco, shown as a curious bump on the profile graph. Here a concrete dam forces the rider onto a very steep single track climb followed by true life-or-death exposure and a handful of gnar switchbacks. That this surprise section appear well after the main challenge is reason for caution. Dec 22, 2018
