Old Fall River Road was opened in 1920, and was the first auto route in Rocky Mountain National Park offering access to the park's high country. Old Fall River Road is a "motor nature trail” to be traveled at a leisurely pace while enjoying the vistas and flowers.
Trail Ridge Road is one of ten America's Byways and a national designated All American Road. Covering 48 miles between Estes Park and Grand Lake, Trail Ridge Road travels from evergreen forests to alpine tundra and gives visitors thrilling views of the mountains.
Rollins Pass (a.k.a. Corona Pass) sits approximately five miles east and above Winter Park, between Winter Park and Rollinsville. The pass is traversed by two unpaved roads, mostly the former roadbed of the Denver and Salt Lake Railway, which abandoned the route in 1928 when the Moffat Tunnel opened to replace it. This high altitude railroad was known as the Moffat Road. The Boulder Wagon Road, which predates the rail route, also uses Rollins Pass to cross the Continental Divide. Incredible views abound!
