A public commuter bus runs between Denver and Fort Collins: the Bustang North Line. It runs from Union Station in Denver (where Amtrak stops) to the transit center in downtown Fort Collins with only two stops (I-25 at US-34 in Loveland and the Harmony Transfer Center at I-25 and Harmony Road in) Fort Collins).
The bus runs mainly during commuting times, only a few buses at weekends. At this point in time, the last service going north leaves Union Station on weekdays at 7:00 p.m. or Sundays at 7:30 p.m. Since Amtrak long-distance trains are often late, you want to have a backup plan. However, this can be a convenient and economical option if you arrive on time.
The fare from Denver to Fort Collins is $ 10. The bus has a large luggage compartment and free WiFi.
