To get to Rocky Mountain National Park from Aspen, Colorado, you have several options. It is possible to wind your way along mountain highways and across to the western entrance along Highway 34. The most direct route is to head east on Interstate 70, and then north on Highway 40, which will lead to the town of Granby and then Highway 34. Another popular idea is to combine Denver, Boulder, Estes Park and Rocky Mountain National Park on one big excursion from Aspen. This route allows you to travel primarily on freeways, and see some of the more famous hot spots of Colorado. During the winter, the road the traverses the park is closed, so you'll have to pick one route or the other. During the summer, however, consider making one big loop in order to see it all!
If you are in Aspen without transportation at your fingertips, it is possible to sign up for guided hiking or bus tours of Rocky Mountain National Park. Let someone else do the driving! Meet new people and travel more safely through bear country in a group of people.
