The Mount Harrison climb in Idaho via Howell Canyon Road is a long 14.6 mile, paved ascent leading to the state's highest road summit at approximately 9,265 ft. Prepare for a sustained effort, averaging a steady 5.6% with ramps reaching up to around 10%, demanding endurance rather than tackling brutally steep pitches. Along the way you'll experience spectacular panoramic views opening up as you climb towards the fire lookout. Services are non-existent, so go fully self-sufficient. Crucially, check Sawtooth National Forest road status before attempting, as this high-elevation road is seasonally closed due to deep snow in late April, typically opening only in June or July.
