The largest national park in the US — bigger than Switzerland — with nine of the continent's sixteen highest peaks.
Late June–August: warm, long days, with the McCarthy Road open and clear days for flightseeing.
Very few visitors, mostly in July and August.
The McCarthy Road is rough gravel and flat tires are common. Rivers swell in summer, weather can ground flights, and winters are severe.
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.
