The trail is part of the Natura 2000 sites of Karla-Mavrovouni-Kefalovryso-Velestino and Mt Mavrovouni, which are areas of rich biodiversity. Even expert hikers consider this trail difficult, chiefly because it covers more than 14 km (around five hours walk) in a single direction. However, if you plan ahead and opt to stop at various points of interest, you can make a great day of it. Regional authorities are working on numerous plans to revamp the area and add museums, ecological, hiking, riding, cycling and bird watching facilities and more. For now there are also lovely views of Lake Karla as well as stopovers at the chapels of the Transfiguration of the Saviour, Saint Panteleimon, Saint Paraskevi and Saint Athanasios in Ano Kanalia.
