This is one of the most hiked mountains in the world for good reason (often claimed to be 2nd, after Mt. Fuji). Depending upon trail, weather, and time constraints, hike difficulty and grade can vary from easy to difficult. I generally prefer the White Dot Trail, but this can be a tougher, steeper, and more challenging at times. Overall, I would not judge this mountain to be a tough hike (I'm in my late 20's, in good shape, though I don't exercise regularly), and certainly family friendly. Take ten minutes time and read up on your trail options before driving out- it's worth it. As with any hike to be enjoyed, plan on breaks and move at a comfortable pace, regardless of trail. The views are truly incredible on clear days and the uniqueness of the bald peak at such a lower elevation gives one the impression of having done more climbing than you actually have. Certainly beautiful, best, and most stunning in the autumn foliage, but fantastic year-round.
