Casa Navarro State Historic Site is a state park in Bexar County, Texas. It is listed on the National Register of Historic Places.
Casa Navarro is a historic site in San Antonio, Bexar County, Texas, United States. The original house complex was the residence of Texas patriot José Antonio Navarro (1795–1871), a rancher, merchant, leading advocate for Tejano rights, and one of only two native-born Texans to sign the Texas Declaration of Independence. Navarro first bought the property, about 1.5 acres, in 1832. The limestone, caliche block, and adobe structures were built c. 1832–1855, and Navarro moved onto the property soon after.From the Wikipedia article “Casa Navarro”, 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 Casa Navarro State Historic Site, 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 7 (suburban / urban transition), so expect visible sky glow; drive away from towns for better results.

Estimated sky darkness: 7 Bortle 7 — Suburban / urban transition. The whole sky has a grey-white glow; the Milky Way is invisible to the eye. Modeled zenith brightness ≈ 18.9 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.
