Chimney Rock is a rock formation in Frederick County, Maryland. It lies in or next to Catoctin Mountain Park, so park hours, fees and rules apply. The nearest town is Thurmont, about 2.0 km (1.2 mi) away (Chimney Rock lies WNW of town).
From the National Park Service
Chimney Rock is at about 1,400 feet in elevation and looks out to the east over the piedmont region. The ourcrop is part of the larger Weverton Formation, with the weather-resistant quartzite forming the "chimney" after millions of years of erosion.

Golden hour & blue hour by month
Rock towers and buttes glow red and orange in the first and last half-hour of sun; midday light flattens their shape.

Local time (America/New York), including daylight saving time. Golden hour runs from about −4° to +6° solar altitude, so the morning golden hour begins during blue hour, before sunrise.
Milky Way & night sky
From Chimney Rock, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 4.8 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 5 (suburban sky), so expect visible sky glow; drive away from towns for better results.

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: 5 Bortle 5 — Suburban sky. The Milky Way is weak near the horizon and washed out overhead; long exposures pick up a sky glow. Modeled zenith brightness ≈ 19.85 mag/arcsec². Aurora needs roughly Kp 7.0+ 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 52% average cloud cover) and December as the cloudiest (66%). 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 rock formation
- Find a spot where the formation sits against open sky to emphasize its silhouette.
- At night, a formation under the Milky Way or star trails makes a strong anchor.
- Use the sunrise and sunset azimuths below to know which face will be lit.
- Stay on trails; desert soils and lichens take decades to recover from footprints.
- Shoot RAW to keep the most latitude for high-contrast sunrise and sunset scenes.
Season: Spring and autumn are best in desert regions; winter snow on red rock is rare but spectacular.
Suggested gear: Wide and telephoto lenses, Tripod, 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.
