Climbing the Mt. Flume and Liberty via Liberty Spring Trail Loop

From Franconia Notch, the Flume Slide Trail climbs open slabs to the sharp summit, while the Liberty Spring Trail offers a safer alternative. The slide is a steep Class 3 scramble on rock that is dangerously slick when wet, so most hikers ascend it and descend via Liberty. Flume gives a dramatic pointed summit with big drops and views down Franconia Notch. The top is exposed to wind. Start early, avoid the slide in rain, and carry layers. Nearly always combined with Mount Liberty just to the north.
