Located in Fresno County, California, Muir Pass is a mountain pass at about 3,650 m (11,975 ft) above sea level. It is part of Kings Canyon National Park. The nearest town is West Bishop, about 34 km (21 mi) away (Muir Pass lies SW of town).
Muir Pass is a mountain pass in the Sierra Nevada of California, United States, in Kings Canyon National Park. It is named for John Muir. The pass is near the midway point of the John Muir Trail and around mile 841 of the Pacific Crest Trail. It crosses the Goddard Divide between Mount Solomons and Mount Warlow, at an elevation of 11,955 feet (3,644 m). The Muir Hut, built by the Sierra Club, is at the summit of the pass. Although the grade is gentle from both directions, snow can persist well into the summer, obscuring the trail for miles.From the Wikipedia article “Muir 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.

Milky Way & night sky
From Muir Pass, the Milky Way core is visible in a dark sky from March through October. June gives the longest window (about 5.5 hours on a moonless night), and the core peaks around 24° above the southern horizon. Our light-pollution model puts the sky at about Bortle 2 (typical truly dark site), which is excellent for astrophotography.

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: 2 Bortle 2 — Typical truly dark site. The summer Milky Way shows rich structure; clouds look like black holes in the stars. Modeled zenith brightness ≈ 21.78 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show September as the clearest month (about 21% average cloud cover) and December as the cloudiest (54%). July is the warmest month and January 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.
- Check road status before driving: many high passes close seasonally or after storms.
- 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.
