Bustang to Fraser With a Bike — Ride Home to Denver, Ride There for the Day, or Ride to the Next Stop

▼ 3,374 ft net descent to Denver Union Station
Fraser Amtrak Station · 205 Fraser Ave. · Craig Outrider

The Fraser valley is the classic version of this trip: bus up US 40, then ride home over Rollins Pass on the old Moffat Road railroad grade and down into Boulder County. Dirt, history, and about 3,300 feet of net drop.

🚲 2 rack spaces guaranteed — more usually fit underneath

Bustang's published limit is two bikes on the rack, first-come first-served, with no reservations. In practice the under-bus luggage bay takes more: riders regularly get three or four bikes on a mountain run. Mountain bikes go in the bay with the front wheel off; gravel bikes usually fit underneath as-is, wheels on.

Rack rules: Bustang FAQ. Real-world capacity from riders who have done it — treat the bay as likely, not guaranteed.

The ride back to Union Station

Same start, same finish, three different bikes — the route changes with what you are riding, not just the surface mix. All three finish at Denver Union Station; plan it to your own address if you live somewhere else.
