This "park in the sky," which captures the full grandeur of the Rocky Mountains, is one of our country's most frequently visited national parks, attracting more than three million visitors each year. 76 of the great mountains in the park reach elevations of 12,000 feet or more. Forests of spruce and fir tower over wide valleys where aspen and willow line hundreds of streams and lakes. At the highest elevations, above the tree line, is the fascinating, arctic-like alpine tundra, fraught with blizzards in winter and filled with flowered meadows in summer. All this is just 65 miles northwest of Denver! Rocky Mountain National Park offers visitors an enormous variety of things to do throughout the year, ranging from all snow-related activities during the winter, to hiking, biking, camping and fishing during the summer.
