Thousands of hoodoos — spire-shaped rock pillars — create an alien amphitheater of orange and red at 8,000 feet.
May–June and September–October: comfortable temperatures at 8,000+ feet, clear skies and shorter lines at viewpoints.
June–August is busiest, with shuttles and viewpoints packed midday. Winter is quiet.
Winter brings snow, freezing nights and some closures (the hoodoos in snow are spectacular). Summer afternoons bring thunderstorms.
General patterns — conditions vary by year. Check current NPS alerts and road status before you go.
Distances are rough estimates to the closest entrance. Check road and ferry conditions before you go.
Campgrounds inside the park are booked through Recreation.gov, and many fill months ahead.
