Denver Union Station
What used to be a nondescript train station has become the most popular spot in Lower Downtown thanks to a $500 million renovation. As the city's transit headquarters and the end stop for the train to the airport, Denver Union Station is home to seven restaurants, the 112-room Crawford hotel, and even a kids' fountain located on the pedestrian plaza outside in the summer. Check out the farmer's market that runs from early June through the end of October, satisfy your sweet tooth with a trip to the Milkbox Ice Creamery, and marvel at the historic train station architecture.
