Any week of Scottish Winter walking/climbing but especially proposing to my now wife on Ben Starav after ascending iced-up north ridge.
Middlefell Buttress. First multipitch lead on a perfect day and lovely dip in a stream on the way down.
Normal route on Mont Blanc de Cheilon. First apline lead.
Aonach Eagach & An Teallach - they really are as good as people say!
