I did a mountainbike tour with Stelios Epitropakis the owner of Cycling Creta. He is a professional and very passionate and friendly guide and mountain biker. The equipment (bikes, helmets, etc.) was great and completely new.
You can choose between tours of different levels from beginners to professionals. Stelios not only knows all the little nice paths in the mountains of Crete but also a lot about the island, its nature, culture, history and the people. So, on a tour with him you can not just enjoy the beauty of Crete with its fantastic mountains but also have a nice talk with the guide and learn more about Crete.
I can highly recommend Cycling Creta!
