In reply to geoff.comley:
I did a Winter Climbing course with them and when i went they teamed me up with another of similar abillity and we were designated an instructor for the week (Andy Turner), the instructor asseses your competance as the week goes on and decides how hard the climbing needs to be. we did a grade 3,4 and 5. i had a great week and couldn't speak higher of the staff, the accomodation, the food, the facillities, the Mountain Instructors and the evening seminars. I learned a great deal that week.
Tip, if you have far to go to get there a National Express to Aviemore cost me £39 return from London Victoria.
