Airport Rail

At a cost of $10 each way, travelers can use the A Line to get from the airport to downtown Denver and vice versa, courtesy of the Regional Transportation District (RTD), metro Denver's public transit provider.

The A Line, which opened on April 22, 2016, whisks travelers to the heart of downtown, specifically Denver Union Station, which is the city's transportation hub and "living room," thanks to its plush surroundings. From Union Station, travelers can access additional local and regional transportation services, such as light rail, regional and local buses, Amtrak rail service, taxis and the free 16th Street Mall shuttle (MallRide) and free downtown MetroRide buses that provide access to most downtown hotels. Union Station itself is a beautiful 1914 Beaux-Arts building and the location of a number of hip, locally owned restaurants, bars, shops and a boutique hotel, The Crawford Hotel.

The Denver airport rail has six stops between the airport and Denver Union Station. The 23-mile ride takes approximately 37 minutes.
