The Danny On National Recreation Trail is an outdoor recreation area in Whitefish, Montana. It is located inside the Flathead National Forest on the Tally Lake Ranger District. It is the most popular trail in the area, receiving up to 15,000 visitors per year.

Named after the silvaculturist or applied forest ecologist, Danny On, the Danny On National Recreational Trail was built in his memory after his death on 1979 in a skiing accident. The trail is quite a noted site among hikers and nature enthusiasts. It is actually one of the few national recreation trails in the US that can be accessed by chairlift. Hikers also have the choice to ride the chair up the mountain and hike the trail downwards.
