You have 1,440 minutes in the Mile High City, so grab a light coat and get moving.
Morning
We’ll start at Union Station because that’s where you’ll end up if you arrive by Amtrak or take the train into town from the airport. Start the morning walking around the station. The 100+-year-old building was remodeled in 2014 to include the hotel, restaurants and pubs, additional train lines, and to serve as the general hub for downtown visitors.
