Tons of elevation gain, if you're tired there are a few places you can go to avoid the steep part of the trail and meet back up with the route. Bring hiking poles for one extremely steep downhill section if you like the extra stability.

wide enough for 2-way traffic; some blind spots, so be careful. Trail is smooth, so downhill bikers are often riding pretty fast.
