Milky Way & dark skies
From Manhattan Project, the Milky Way core is visible in a dark sky from February through October. June gives the longest window (about 5.7 hours on a moonless night), and the core peaks around 25° 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.

| January | Not visible in darkness | — | — |
| February | 4:53 AM – 5:23 AM | 0.5 | 15° |
| March | 3:58 AM – 5:48 AM | 1.8 | 22° |

5 Estimated Bortle 5 — Suburban sky. The Milky Way is weak near the horizon and washed out overhead; long exposures pick up a sky glow.
Weather & best time to visit
The Manhattan Project National Historical Park has units in Hanford, WA, Los Alamos, NM, and Oak Ridge, TN. Check local weather conditions at each unit before you visit.
Weather overview: National Park Service.
Long-term NASA satellite data for this area show October as the clearest month (about 32% average cloud cover) and July as the cloudiest (52%). July is the warmest month and January the coldest, which matters for gear, snow access and how long batteries last at night.

Photography permits, drones & fees
Permits. 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.
Getting there
Manhattan Project National Historical Park is located in three states: New Mexico, Tennessee, and Washington. For more information on accessing each of these three units, visit our Directions & Transportation page.
