Stargazing in Warrumbungle National Park / Siding Spring Observatory, New South Wales (2026)

Bortle 2 · International Dark Sky Park (DarkSky International)
🌠 Geminids 2026 — watchable from the Southern Hemisphere too. Unlike the Perseids, the Geminid radiant is far enough north of the celestial equator to remain genuinely visible south of the equator, just at reduced rates. The shower peaks the night of Dec 13–14 under a dark, moon-free sky; the best window here runs midnight through dawn, facing generally north toward Gemini. Before you go: Warrumbungle National Park is always open (may close for fire/weather) - campers and visitors can stargaze freely at night from campgrounds and roadside spots. From this site, expect roughly 30–60 meteors an hour at peak from a dark site. December is summer here, so no cold-weather gear needed — just the usual dark-sky basics. Full Geminids 2026 guide →

What is Bortle 2?

Truly dark: M33 (Triangulum Galaxy) is easy to see naked-eye, the Milky Way looks like veined marble, and clouds appear as dark holes in the stars.
