I was extremely disappointed that the leader thought I was not fit enough to take part in the walks, without any justification. I would not have booked the holiday if I thought I was not fit enough, as it would be unfair on other guests and I would not have enjoyed that. I have been taking part in walking and other activity holidays for many years, and am well aware of my capabilities. I was not allowed to take part in the glacier walking trip, the main reason I booked the holiday - even though the guidebooks said there were trips for all levels of ability, and I have done glacier walking before. I have never enountered any problems before.
