The route is also variously known as the Tourist Track or Pony Track – probably because it goes up a mountain and the path is well enough made that you could take a pony up it. There may be more serious historical reasons behind the names, but it helps you get an idea of the path: compared with the more demanding CMD (Carn Dearg Meadhonach) scramble ridge, it’s the simple option.
Ben Nevis is purportedly the hardest mountain (and highest peak) of the Three Peaks Challenge. That’s why people tend to do it first. You get a great feeling of accomplishment as you make it to the summit and can kind of convince yourself that it’s all downhill from here… taking in the highest peak in England and highest peak in Wales kind of way!
