Grizzly Flat Rd. drops from Mt. Lukens Truck Trail #3N27
all the way to Grizzly Flats, a remote, rarely-used trail camp on the Big Tujunga side of Mt. Lukens. From there, the Grizzly Flats Trail continues down into Big Tujunga Creek. The portion of this road between the intersection with Hoyt Mountain Road
and Grizzly Flats is rarely used.
If you're climbing Mt. Lukens Truck Trail #3N27
from the Fire Station and want some variety, take Grizzly Flat Rd. to the intersection with Hoyt Mountain Road
and either continue straight onto Hoyt or go right for the Upper Dark Canyon Trail
. Both end on the Angeles Crest Hwy 2, which you can then descend back to the Fire Station.
A fire access road, Grizzly Flats Rd. cuts a wide bench in the steep flank of Mt. Lukens. The trail you'll follow is a snaky, smooth line that meanders across the road, avoiding cinderblock-like boulders, downed trees, and the occasional landslide. Overgrowth can make the trail quite narrow at times. The shadier contours of the mountain have tall pine trees, while the sunnier and lower sections are a similar chaparral to what you might find way down in Arroyo Seco.
