1 certified dark-sky destination within 100 miles · Nearest: Enchanted Rock State Natural Area (77 mi N)
Enchanted Rock State Natural Area is just 74 miles north of the Alamo City on US-281 and Ranch Road 965 — Texas's only certified International Dark Sky Park and a practical evening trip. The park publishes live Sky Quality Meter readings every 15 minutes, which is rare and useful for pre-trip planning. Gate closes at 8 PM; book a walk-in campsite for summer visits to be there after dark.
🌠 Perseids 2026 — a rare moonless peak. The shower peaks overnight Aug 12 into pre-dawn Aug 13 on a new moon, so the sky stays fully dark all night — the best Perseid conditions in years. These skies offer a strong Perseid showing — peak overhead rates depend on exact Bortle conditions on-site. Best rates 2–5 AM local time; no equipment needed, just look up.
