Bunsen Peak prominently sits south of Mammoth Hot Springs. From this trailhead, you can embark on the following trails: Bunsen Peak Trail Bunsen Peak Road Trail Osprey Falls Trail Parking is limited. Winter trailhead access requires a snow coach drop-off, or skiing up from the gate at the Upper Terrace parking lot. Bunsen Peak Trail A moderate 4.2-mile (6.7-km) there-and-back trail to the summit of Bunsen Peak. Although this is a relatively short hike, the elevation gain is 1,300 feet (396 m) over 2.1 miles (3.2 km) of switchbacked trail. CAUTION: Grizzly bears frequent this area. Bunsen Peak Road Trail A 6-mile (9.6-km) one-way, moderate trail that follows an old service road curving around the southern and eastern sides of Bunsen Peak. The first 3 miles (4.8 km) are mostly level. On the northeast side of Bunsen Peak, the road becomes steep and winding, dropping 960 feet in 2.5 miles (292 m in 4 km) to Glen Creek. CAUTION: Some curves have steep drop-offs and can be hazardous when icy. Osprey Falls Trail A strenuous, 8-mile (12.9-km) there-and-back trail that descends into one of the deepest canyons in the park.

Golden hour & blue hour by month
Overlooks are about the sweep of the land, so low-angle light matters most: side-light at sunrise or sunset reveals ridges and texture that midday sun flattens.

Milky Way & night sky
From Bunsen Peak Overlook, the Milky Way core is visible in a dark sky from April through August. June gives the longest window (about 3.2 hours on a moonless night), and the core peaks around 16° above the southern horizon. Our light-pollution model puts the sky at about Bortle 1 (excellent dark-sky 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: 1 Bortle 1 — Excellent dark-sky site. The Milky Way casts faint shadows; zodiacal light and airglow are obvious. Modeled zenith brightness ≈ 21.93 mag/arcsec². Aurora needs roughly Kp 5.5+ to show low on the northern horizon here.
Weather & best season
Long-term NASA satellite data for this area show July as the clearest month (about 39% average cloud cover) and February as the cloudiest (77%). 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 scenic viewpoint
- Haze builds in summer afternoons; mornings after a cold front are often the clearest.
- Stay behind barriers — many overlook edges are undercut or crumbly.
- A panorama of 3–5 vertical frames gives more resolution and a wider view without a fisheye look.
- Blue hour after sunset is excellent for towns or roads below the viewpoint as lights come on.
- Arrive 30–45 minutes before sunrise or sunset to find a composition before the light peaks.
- Shoot RAW to keep the most latitude for high-contrast sunrise and sunset scenes.
Season: Clear, dry air in autumn and after winter storms gives the longest views; summer adds wildflowers but also haze.
Suggested gear: Tripod, Telephoto lens, Graduated ND filter, Headlamp. 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.
