There's a few ways, just don't end up on I-70 Things...
The two most popular airports for accessing the Vail Vailley are Eagle (EGE) & Denver International (DEN). Denver is the most reliable & high-traffic hub, serving most major airlines & routes, lots of shuttles & rental car options - expect a 2-3+hr drive depending on traffic. Meanwhile, Eagle Airport is just a stone's throw away & a quick shuttle ride to Gravity Haus Vail - most flights to EGE are connected through the DEN & are very weather dependant.
Mountain Ready Rides offers scheduled airport shuttles & private charters to and from Denver International Airport, Eagle Airport & beyond
There are also multiple car rental options available - we recommend an AWD or 4x4 in the winter - it's actually the law.
