Totally worth it. Transportation is comfortable, some parts of the journey are bumpy and could cause dizziness. Breakfast and lunch are very good. Don't expect a 5-star hotel buffet, but for the price it's not bad at all. The climb is moderately intense. If you don't feel ready, you can rent horses for 80 soles, but only for the climb. The descent is on foot. I recommend wearing sunscreen and a hat. It's a unique experience that's totally worth it.
