From what I've read and heard, you can go the tough way with it, or the easy way.
Easy way being you more or less follow a trail for about 2-3 hours, no special equipment needed or anything, then you can drop in at assigned spots that someone can go over with you on a "trail map" before you head up.
Or you can go the tough way which I've heard involves going off the main trail going up and can get pretty dicey if you've never climbed before.
From the few people I've talked to that have done it, they've done it in April/May and brought beers up with them and had a good time, so I don't think it's super strenuous if you don't want it to be.
I'd be up for somewhere inbetween, but because I don't have any specializd equipment then I guess I'd be opting for the easier route.
