Ben Nevis is only 1,400 meters above sea level, but it is the highest peak in the UK. Because the hiking trails that are only a few miles away from Fort William are called tourist-level trails, I am confident that I was on a rainy morning in October but thought it was a walk, only in a casual sportswear, without carrying any water and food. The road, although the trail administrators who met me reminded me that the snow on the top of the mountain is very difficult and safe, but I still don't think so. The wind in the mountainside, the stream that entered the river, the rain and snow with almost zero visibility after halfway, the low-level equipment, less than 3 hours, drenched, quickly lost temperature, can only fail and return. It seems that the highest peak of snow on every mountain top is worthy of respect.
