La Poudre Pass is a mountain pass in Grand County, Colorado at about 3,104 m (10,184 ft) above sea level. It lies in or next to Rocky Mountain National Park, so park hours, fees and rules apply. It sits roughly 28 km (17 mi) WNW of Estes Park.
La Poudre Pass (elevation 10,184 ft (3,104 m)), a high mountain pass, is located in the Rocky Mountains of northern Colorado in the United States. The pass straddles the Continental Divide, and separates the headwaters of La Poudre Pass Creek, which joins the Cache la Poudre River and eventually empties into the Gulf of Mexico, from the headwaters of the Colorado River, which drains into the Gulf of California. At the pass, the Continental Divide is the boundary between Grand and Larimer counties, and is also the northern boundary of Rocky Mountain National Park. The pass itself is a broad, flat, swampy area. In the wet meadow just south of the divide, the Colorado River begins its course as a tiny stream emerging from this area which includes the small La Poudre Pass Lake. The Rocky Mountain National Park La Poudre Pass Ranger Station is also located in the pass. The pass is...From the Wikipedia article “La Poudre 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 La Poudre Pass, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 4.7 hours on a moonless night), and the core peaks around 21° above the southern horizon. Our light-pollution model puts the sky at about Bortle 3 (rural sky), good enough for detailed Milky Way images.

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: 3 Bortle 3 — Rural sky. Some light domes sit on the horizon, but the Milky Way still looks complex overhead. Modeled zenith brightness ≈ 21.56 mag/arcsec². Aurora needs roughly Kp 7.5+ to show low on the northern horizon here.
Weather & best season
Long-term NASA satellite data for this area show September as the clearest month (about 46% average cloud cover) and May as the cloudiest (67%). 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
- 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.
- 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.
- Shoot RAW to keep the most latitude for high-contrast sunrise and sunset scenes.
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.
Permits, drones & access
National Park Service rules. Under federal law (54 U.S.C. 100905), still photography in National Park Service areas needs a permit only when it (1) takes place where members of the public are not allowed, (2) uses models, sets or props that are not part of the location's natural or cultural resources or administrative facilities, or (3) would cause the park to incur additional administrative costs to monitor the activity. Ordinary visitor and most landscape photography needs no permit. Commercial filming rules are separate and have changed in recent years — confirm current requirements with the park before a paid shoot.
Drones: Launching, landing or operating unmanned aircraft (drones) is prohibited in National Park Service units under a 2014 Superintendent's closure (36 CFR 1.5), except where a park has issued specific written approval. Flying from outside the boundary over park land can also violate park rules and disturb wildlife.
