← Ontario Night Sky · All sites tonight
No-go (High confidence)
Overcast: mean cloud 100%, minimum 100%. Sit this one out.
No clear window of 2+ hours during tonight's astronomical night.
Grasslands National Park protects Canada's last stretch of untouched mixed-grass prairie, and its Dark-Sky Preserve designation is almost redundant — with no towns for many kilometres in any direction, the Frenchman Valley area delivers a true Bortle 1 horizon-to-horizon sky. This is as close as the Prairies get to a planetarium ceiling.
Drive from Toronto: Fly into Regina, then drive about 3 hours south-west to the West Block near Val Marie.
Best time of year: Late summer through autumn — dry prairie air gives exceptional transparency, and the park runs occasional public astronomy events.
