Growing up, I belonged to the Horseman's Association, and we would often to trailriding all day, and occasionally, we even went on an overnight trail ride. The last trail ride that I went on was about 10 years ago, and I was still not quite 60, and used to horseback riding several days a week. Even so, this was a challenging trail ride.
There were four or five us, and we rode up to a place called "Goat Mountain", which is actually on the list of highest peaks in Idaho. The trail was an old Forest Service trail, and used when they went up to the lookout during fire season. They made the trp with pack mules, which are a lot more sure-footed than any horse is.
The trail had not been used since the year before, and there were a lot of downed branches and even a few trees, that we had to either cut with the handsaw, or try to pushoff of the trail, or go around when that was possible.
It must have taken us 3-4 hours of riding to get to the top, and parts of the trail, we had to dismount and lead the horses, it was so narrow. At the top, we gladly ate our sandwiches and drank our water, and gave both the horses and ourselves a much needed break before heading back down again.
The trip down went much faster, probably only a couple of hours, but still needing to lead the horses through the bad (read scary here) parts. I was totally exhausted by the time I got home that night, and so ready for a hot shower and a long night's sleep! The highest green mountain on the left with the long bald slope is where we rode to. The bald slope near the top is where it was straight up and down, and we had to dismount and lead the horses.
