Trail Map

Mount Flume Trail Map


Flume Slide Trail – 9.6 miles round trip, 3,100 feet elevation gain

The flume slide trail is a very steep but gorgeous trail that begins just after the Flume Visitors center.

Osseo Trail – 11.2 miles round trip, 3,150 feet elevation gain

This trail begins at the Lincoln Woods Parking area along the Kanc. This trail is less traveled and less steep than the flume slide trail. This is a section of trail that is hiked most often for the Pemi Loop.

Mount Liberty and Mount Flume Loop – 9.9 miles round trip, 3,750 feet elevation gain

This loop trail is highly recommended. This is the best way to tackle both of these 4,000 foot mountains. You can choose to go up the flume slide trail (recommended), or up the Liberty Springs Trail.

Additional Information

Mount Flume is an awesome hike. If you are a fan of steep trails with a little bit of rock scrambling, the flume slide trail is a must. In winter months, the flume slide trail is extremely ice and difficult. Crampons/microspikes are absolutely required. The trail features gradual gains until about the last 1.5 miles where you get the majority of your elevation gain.

The Mount Liberty and Flume loop is a fantastic day hike and is highly recommended.
