Cajon Pass is a mountain pass in San Bernardino County, California at about 1,169 m (3,835 ft) above sea level. It sits roughly 7.7 km (4.8 mi) SW of Oak Hills.
Cajon Pass (; Spanish: Puerto del Cajón or Paso del Cajón) is a mountain pass between the San Bernardino Mountains to the east and the San Gabriel Mountains to the west in Southern California. Created by the movements of the San Andreas Fault, it has an elevation of 3,777 ft (1,151 m). Located in the Mojave Desert, the pass is an important link from the Greater San Bernardino Area to the Victor Valley, and northeast to Las Vegas. The Cajon Pass area is on the Pacific Crest Trail. Cajon Pass is at the head of Horsethief Canyon, traversed by California State Route 138 (SR 138) and railroad tracks owned by BNSF Railway and Union Pacific Railroad. Improvements in 1972 reduced the railroad's maximum elevation from about 3,829 to 3,777 feet (1,167 to 1,151 m) while reducing curvature. Interstate 15 does not traverse Cajon Pass, but rather the nearby Cajon Summit, 34°20′58″N 117°26′47″W....From the Wikipedia article “Cajon Pass”, licensed under CC BY-SA 4.0.

Golden hour & blue hour by month
Mountain passes sit above valleys, so they reward sunrise and sunset with layered ridges, valley fog and long shadows.

Local time (America/Los Angeles), including daylight saving time. Golden hour runs from about −4° to +6° solar altitude, so the morning golden hour begins during blue hour, before sunrise.
Milky Way & night sky
From Cajon Pass, the Milky Way core is visible in a dark sky from February through October. June gives the longest window (about 6.0 hours on a moonless night), and the core peaks around 27° above the southern horizon. Our light-pollution model puts the sky at about Bortle 5 (suburban sky), so expect visible sky glow; drive away from towns for better results.

Window when the galactic core is at least 10° high during astronomical darkness on the 15th of each month. Pick nights within a few days of the new moon. Plan exact nights with the Milky Way planner.
Estimated sky darkness: 5 Bortle 5 — Suburban sky. The Milky Way is weak near the horizon and washed out overhead; long exposures pick up a sky glow. Modeled zenith brightness ≈ 19.62 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show September as the clearest month (about 14% average cloud cover) and January as the cloudiest (44%). July is the warmest month and December the coldest, which matters for gear, snow access and how long batteries last at night.

Photography tips for this mountain pass
- Look for the road itself as a leading line — switchbacks from above make strong compositions.
- Weather changes fast at elevation; carry layers even in summer.
- Summit pull-outs often face one direction; use the sun azimuth table to see whether sunrise or sunset suits the view.
- Wildflowers bloom late at pass elevations — often July to early August in the Rockies and Sierra.
- Tell someone where you're going in remote areas and carry the ten essentials.
Season: Summer and early autumn are the main season; winter visits depend on plowing and avalanche conditions.
Suggested gear: Telephoto lens, Tripod, Warm layers, Road-condition app. Work out exposures with the depth of field, ND filter and NPF rule calculators.
