About the Hike:
The high peaks of the Franconia Range have long been famous for their breathtaking views of the Pemigewasset Wilderness and are proportionately popular, but the two mountains at the low end of the range, Mt. Liberty and Mt. Flume, are far less visited. Their views are nearly the same, but Mt. Flume's view is restricted by trees in one direction. For this reason, regular hikers will probably want to ascend only Mt. Liberty. 4000-footer climbers will need to get to Mt. Flume. To include Mt. Flume and Mt. Liberty in one trip, you can ascend the infamous Flume Slide Trail. This trail ascends over the path of one of the mountain's old landslides and involves much rock scrambling of great difficultly. This trail should only be attempted by experienced hikers, and you should never descend this trail.

Since there is no parking at the beginning of the Liberty Spring Trail, the hike starts on the Whitehouse Trail, an easy path running parallel to the road. Leaving the parking area, the trail climbs around a few small hills for 0.6 miles, then joins Franconia Notch Recreation Path (turn left) for a pleasant stroll along the Pemigewasset River. Just after Cascade Brook Trail leads off to the left, the bike path turns right to cross a bridge. On the other side, turn right onto Liberty Spring Trail. The trail heads straight into the forest for a short distance, then two long, moderate switchbacks lead to the junction with the Flume Slide Trail, 0.6 miles from the bike path. Turn right and follow Flume Slide Trail as it heads off across the slope at a flat grade, occasionally descending. In 0.3 miles, the trail crosses two brooks. It now climbs gradually through an open forest, crossing many more brooks along the way. After almost two miles of winding through the woods and crossing streams, the trail arrives at a larger brook, Flume Brook. This brook is the source of Avalanche Falls, a popular tourist attraction at the Flume Gorge. The trail crosses it twice (difficult in high water), then continues up along the bank, where you can glimpse Mt. Flume and Mt. Liberty above. The trail then crosses the north fork of the brook, the last water crossing, and climbs away. The trail surface changes to gravel as it nears the slide, and the incline steepens rapidly. Soon, you will reach the bottom of the slide. For the next half mile, the trail ascends extremely steep rock slabs, which are often wet and slippery. Good foot placement and use of hands is necessary. Blazes are few, but the route is usually obvious. Some of the trickiest scrambles can be avoided by staying toward the forest on the sides (usually the left side is best). Halfway up, look for a limited view of Mt. Moosilauke behind you. Near the end, the grade lessens. At the top of the slide, the trail turns sharply left and continues to climb very steeply through the forest for 0.2 miles to a trail junction. Turn left onto Franconia Ridge Trail as it climbs much more easily for 0.1 miles to the sharp summit of Mt. Flume.

From the summit, the view is best to the south and west. You can see Mt. Moosilauke to the southwest and the Kinsmans across Franconia Notch to the west. Mt. Liberty and the Franconia Ridge rise above you to the north. Mt. Garfield is directly north, over the valley. Owl's Head Mountain and the Twin Range are visible through the trees to the northeast. Mts. Carrigain and Hancock are seen through the trees to the east. To the southeast, you can see Mts. Osceola and Tecumseh over the trees. To the south, the view extends into the distance.

Since you should not return the way you came, follow the Franconia Ridge Trail to Mt. Liberty. The trail descends moderately from the summit into a wide col, then makes a steeper ascent to Mt. Liberty with some climbing over rocks near the end. It is 1.1 miles from Flume to Liberty. For more information about Mt. Liberty and your descent route, see the link above.
