Government Canyon State Natural Area — a state park in Bexar County, Texas — is a classic subject for landscape photographers. The nearest town is Helotes, about 8.0 km (5.0 mi) away (Government Canyon State Natural Area lies WSW of town).
First opened to the public in October, 2005, Government Canyon State Natural Area (GCSNA) preserves 13,067 acres (52.9 km2; 20.4 sq mi) of rugged hills and canyons typical of the Texas Hill Country. It is designated a Natural Area, rather than a State Park, and therefore the primary focus is maintenance and protection of the property's natural state. Accordingly, access and recreational activities may be restricted if the Texas Parks & Wildlife Department (TPWD) deems such action necessary to protect the environment. The reserve is located in northwestern Bexar County, and protects a large, relatively pristine tract of Hill Country terrain, numerous and diverse species of plants & wildlife, the upper Culebra Creek/Leon Creek watershed, and a critical aquifer recharge zone for the San Antonio Water System.From the Wikipedia article “Government Canyon State Natural Area”, 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 Government Canyon State Natural Area, the Milky Way core is visible in a dark sky from February through October. June gives the longest window (about 6.7 hours on a moonless night), and the core peaks around 32° 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 ≈ 20.22 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show August as the clearest month (about 41% average cloud cover) and March as the cloudiest (61%). August is the warmest month and January the coldest, which matters for gear, snow access and how long batteries last at night.
