First of all I have to define that menalon trail is not an activity that is only at the district of Stemnitsa. It crosses a very big region through many villages and you can walk the parts of it depending on which village you stay. We stayed in Vytina and we walked the path Elati Vytina by the side of mylaon river and its gorge. Absolutely amazing. You can do tis even on your own or with a guide.
