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 . 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.
