This is not for everyone. It is very hard, and one should be fit to enjoy it. It is not like walking up a hill; on a trail one can choose the length of their step. Walking up railway ties, that is not an option. Walking up requires strength and wind, walking down requires not being exhausted from the walk up, and a pair of very strong knees. Again, this hike is only for the fit.
