There is no public transit. A few taxis and rental cars are available, and bikes can be rented in the summer.
Hitchhikers report that getting a lift in Jasper is very easy.
Jasper is small enough that most places can be easily walked to. Tour companies offer bus service to most of the major tourist destination including Maligne Lake, The Columbia Icefields and Miette Hot Springs. The two major companies in town are Brewster and SunDog. Both these companies offer similar tours at the same price. The only difference is the size of the tour group: Brewster uses large buses seating approx. 50 and SunDog has smaller vehicles seating approx. 12.
