Unlike a self-guided tour, an escorted tour takes place on predefined dates, which you cannot change. The other major difference is that a guide will be with you for the entire trip, showing you the way, sharing his knowledge of the flora and fauna and, above all, the culture of the region. It's all organized, so all you have to do is put on your boots and start hiking! The final difference is that you won't be alone. You'll be sharing your stay with a group, often made up of a minimum of 5 people and a maximum of 15.
