Previous Experience/Fitness

You will need to be a fit mountain walker. A head for heights is necessary. Do not under-estimate this challenge. Ascents and descents are demanding. Some ridges are exposed with steep drops. It is far more strenuous and requires more stamina than the National 3 Peaks Challenge.


You will need clothing and footwear that is appropriate for mountain walking conditions. A kit list, estimate timings, route information and training day details will be provided on booking.

Call me for a chat and look at our Listings for the activities and courses.

We are happy to arrange private guiding or instruction to suit requirements.
