Renting a car is always a great option for flexibility and to enjoy the area during your stay. If you'd rather not rent a car, there are a couple of options for transportation:

From the Denver Airport to Estes Park: Take the Estes Park Shuttle from the Denver's Union Station, Denver International Airport, or Denver Greyhound Bus Station to Estes Park. It's $95 round-trip ($55 one-way). Contact (970-585-5151) https://www.estesparkshuttle.com/ for more information.

Around Estes Park: While you're in Estes Park, you can use the Estes Park Shuttle System to get around town.
