Located in Grant County, Wisconsin, Wyalusing State Park is a state park. The nearest town is Prairie du Chien, about 8.4 km (5.2 mi) away (Wyalusing State Park lies SSE of town).
Wyalusing State Park is a 2,628-acre (1,064 ha) Wisconsin state park at the confluence of the Mississippi and Wisconsin rivers in the village Bagley, just south of Prairie du Chien. Wyalusing means "home of the warrior" in the Lenape language spoken by Munsee-Delaware tribes who settled in the area in the 19th century after being displaced from farther east. Five-hundred-foot-high (150 m) bluffs dotted with prehistoric Native American mounds look out over the river valleys. Two park resources have been recognized nationally: the Wyalusing Hardwood Forest is a National Natural Landmark and the Wyalusing State Park Mounds Archaeological District is on the National Register of Historic Places.From the Wikipedia article “Wyalusing State Park”, 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 Wyalusing State Park, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 4.0 hours on a moonless night), and the core peaks around 18° 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 ≈ 21.55 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 September as the clearest month (about 46% average cloud cover) and December as the cloudiest (68%). 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 state park
- 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.
- Weekday mornings are the least crowded at popular viewpoints.
- Shoot RAW to keep the most latitude for high-contrast sunrise and sunset scenes.
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.
