West Entrance: Amtrak to Granby then Taxi
Served by Amtrak, there are passenger train station stops in Fraser/Winter Park (WIP) and Granby (GRA). Granby is about 20 miles to the park entrance, and Fraser is about 30 miles. There is no ticket office or Quik-Trak kiosk at either station, so you will need to secure your tickets ahead of time. More information at www.amtrak.com
There is no public transportation between the train station and the park, but you can take a taxi. The Valley Taxi service will pick you up from Granby and transport you to a park campground or trailhead.
