The trails are looped back to the Interpretive Center so that distances and difficulties can be chosen by skiers. Approximately fifteen percent of the trails are beginner loops, fifteen percent expert , and the remaining are rated intermediate . The beginner and intermediate trails are tracked for classic style while the expert loops are great for skaters.
Skiing is taught daily to the school groups in residence.
