Denali National Park is beautiful at any time of the year but for many visitors, autumn is when the park is at its peak. Each September, for a four-day period beginning the second Friday after Labor Day, the park uses a lottery to sell 400 permits to drive the road for a day. Normally the 92-mile road is accessible only by bus. This gallery of photos offers a glimpse of the park’s scenery and wildlife made during the lottery periods this year, and in 2006 and 2008.
