Is hiking Whitney around May 20 dangerous? I have hiked a fair bit but have only used crampons once before. If I have an ice axe and crampons, is it mostly a matter of endurance or can it be perilous e.g. falling down a crevice or valley.

I have done a day summit once before but that was in Aug when the snow was gone.

I am planning to do it again this year in May but don't want to do it if there's a serious danger of hurting myself.
