For all our tours we use our own "scale of difficulty" which is easy to understand and is made of 4 different levels:
Unexperienced for those who have never hiked before. Recommended tour types: Ʀ Relax
Easy never demanding but pleasant tour with many stops for photos and selfies. Suitable for those who have a minimal hiking experience and prefer to enjoy nature with many breaks. Recommended tour types for this level: Ʀ Relax  Classic ★ Special
Medium this is our most common tour. It requires a normal hiking experience, a stable and safe pace and no fear of heights. During the hike there can be some difficult parts that, if you are afraid, you can face with the help of our guides. Recommended tour types for this level:  Classic ❍ Open ★ Special
Challenging this is the highest level of excursions we can offer. Especially for the tours in the Dolomites guests must have a good hiking experience, no fear of height, adequate shoes and clothes and a stable and reliable pace. Recommended tour types for this level: Ʌ Adventure ❍ Open ★ Special
