The Roadside Trail is a moderately strenuous walk of 1.8 miles (2.9 km), one hour one-way, from Denali Visitor Center via the Tiaga Trail to Park Headquarters and the Sled Dog Kennels, with 350 feet elevation change, up to 15 percent grade, on a 36-inch compacted gravel surface. Highlights include aspen, birch and spruce forests.

Small amounts of airborne pollutants from around the world arrive in Denali every year. Remoteness alone cannot protect the park's clean air. As global human population grows, it is likely that increasing global emissions will affect Denali's air quality.
