← Ontario Night Sky · All sites tonight
No-go (High confidence)
Overcast: mean cloud 94%, minimum 44%. Sit this one out.
No clear window of 2+ hours during tonight's astronomical night.
Zion's sandstone cliffs frame the sky like the walls of a cathedral, and the park's ongoing lighting retrofit has kept its canyon floor genuinely dark despite heavy daytime crowds. Step away from the shuttle stops after sunset and the Milky Way appears between the towering walls of Zion Canyon.
Drive from Toronto: The main visitor center is just inside the South Entrance near Springdale, Utah, off Highway 9.
Best time of year: Spring and fall for cooler nights and lower crowds; new-moon weeks give the darkest skies.
