Strawberry Peak via Red Box Station
A rugged chaparral singletrack that wraps through the interior front country before ascending a sharp prominent ridge. The optional class-2 rock scramble to the highest front-country peak makes this a local badge-of-honor trail.
-
Millard Canyon Falls and Dawn Mine Loop
A shadowy journey through a shaded Altadena stream canyon — boulder-hopping to a small seasonal waterfall, then looping up Sunset Ridge past the gated entrance of an 1890s gold mine tucked into a cliff face.
-
Henninger Flats via Eaton Canyon
A wide smoothly graded fire road climb that tests steady uphill pacing. The destination is a historic mountaintop tree nursery where thousands of experimental pines and cedars overlook the entire LA Basin.
-
Echo Mountain via Sam Merrill Trail
A legendary front-country route out of Altadena following the original 1890s Echo Mountain Incline Railway path. Stone foundations, historic plaques, an echo phone, and sweeping views of the LA Basin await at the top.
-
Inspiration Point via Echo Mountain
The full extension past Echo Mountain’s ruins, entering the shaded folds of Castle Canyon before reaching a historic covered vista point fitted with fixed sighting tubes aimed at Southern California landmarks.
-
Mount Wilson Trail
The historic granddaddy of San Gabriel front-country climbs. Starting from Sierra Madre, 4,700 feet of vertical gain through exposed canyon walls and forested slopes leads to the world-renowned Mount Wilson Observatory summit.
-
Ice House Canyon Trail to Icehouse Saddle
A pristine river-fed canyon through ancient cedar and pine groves with a year-round running creek. Historic stone cabins line the route before rugged switchbacks climb to the massive alpine saddle connecting multiple major peaks.
-
Mount Baden-Powell via Vincent Gap
A masterfully engineered PCT section that scales a 9,396-foot peak via 40 relentless switchbacks through a rare forest of 1,500-year-old Limber Pines. Summit views span the Mojave Desert and the full San Gabriel range.
-
Cucamonga Peak via Ice House Canyon
One of the most demanding and photogenic summit climbs in the San Gabriel front country. After Icehouse Saddle, steep rocky switchbacks lead to a sheer cliff-edge summit with panoramic views dropping over the Inland Empire.
