Hiking the Inca Trail was one of the best experiences in my life. The road to Machu Picchu may be long and difficult sometimes, but the scenery is amazing and so is the reward at the end!.
The people of Inca Trail Reservations organised everything perfectly and they will help you where and whenever they can. Along the way everything is taken care of by the porters and the chef and the guides really try to make the trail a group adventure.
The only thing you have to worry about is to arrive at the start fully prepared and physically in (decent) shape. Vamos ! You can do it!.
