The Loneliest Road is a 1000 mile moderately trafficked point-to-point trail located near Colorado Springs, CO that offers scenic views and is good for all skill levels. The trail is primarily used for hiking, walking, and scenic driving and is accessible year-round.
US Hwy 50, Colorado Springs to Sacramento Hwy 50 from Colorado Springs (Cos) to Sacramento is one of the most beautiful roads in America. Well maintained and helpfully annotated, I'd suggest taking several days (or several return trips) to do it justice. If you appreciate mountains, rivers, clouds and sky, you'll love this trek. You can enjoy the scenery as you drive, but there are many, many opportunities to get off the road and much closer to the terrain.
