​Hi Eira! It is Maite from Spain again! Just a message to tell you that I spent a wonderful week and that both guides (Paolo and Christian) were superb.

Classic 4000ers

Just a quick word of thanks for the course last week. Our guide Tom was excellent and covered a lot of miles to ensure we got the best conditions and great routes in and was always ready with a word or two of advice when needed - please pass my thanks on to him,
