Palouse Falls State Park is a state park in Franklin County, Washington. It sits roughly 43 km (27 mi) NNW of Dayton.
Palouse Falls is a waterfall in the northwest United States on the Palouse River, about four miles (6 km) upstream of its confluence with the Snake River in southeast Washington. Within the 94-acre (38 ha) Palouse Falls State Park, the falls are 200 feet (61 m) in height, and consist of an upper fall with a drop around twenty feet (6 m), which lies 1,000 feet (300 m) north-northwest of the main drop, and a lower fall.From the Wikipedia article “Palouse Falls”, licensed under CC BY-SA 4.0.

Golden hour & blue hour by month
State parks often protect a signature feature — a gorge, lake or overlook — that is best in early morning before visitors and harsh light arrive.

Milky Way & night sky
From Palouse Falls State Park, the Milky Way core is visible in a dark sky from April through August. June gives the longest window (about 2.3 hours on a moonless night), and the core peaks around 14° 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 ≈ 21.8 mag/arcsec². Aurora needs roughly Kp 5.0+ 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 26% average cloud cover) and January as the cloudiest (79%). 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 state park
- Trail maps often mark overlooks — combine them with the sun azimuth to plan.
- Day-use fees or passes are common; buy them online before arriving.
- Check park hours: many state parks close at dusk, which affects sunset and night shooting.
- Ask rangers about photography permits for commercial work, models or drones.
- Bring a spare battery — cold weather and long exposures drain them fast.
Season: Spring wildflowers and autumn color are peak seasons in most parks.
Suggested gear: Versatile zoom lens, Tripod, Park pass. Work out exposures with the depth of field, ND filter and NPF rule calculators.
Permits, drones & access
Drones: Drone rules in state parks vary by state and even by park — many require a permit or ban recreational drone flights. Check the park's rules and the FAA B4UFLY app before flying.
