This seems to take a back seat to many of the other options for excursions in the area and I think it tops most. It is most certainly better than the Colca canyon. This is a relatively accessible mountain and provides you with a fair shake to surpass the 6000m mark which means that while it doesn't require any exacting technical prowess, it is still a buttkicker. You will most likely need crampons which along with all gear you can rent or get included depending on your company. This will be a very full day and a half at some serious altitude and requires some fortitude so dont let the sales-people talk you into this "cake walk". My girlfriend and I are very fit and heavy duty exercisers and this still had us questioning our fitness at times. 6 hours up and two hours down mean that this is a very steep mountain to climb. Good luck, the pictures are worth it.
