Tour from Lacona up to the Mt. Tambone and around the Mt. S. Martino down to Lacona again. Down from Mt. Tambone to the the street (Lacona / Marina di Campo) and down to Locana are some good and difficult downhill trails (left from motor bike trail machines). I did not ride over the Mt. S. Martino, but i marked the step into with a waypoint, if you do, send me the track to add. There is another tour from Locana to the Mt. Tambone, going down to Mariana di Campo and Locana with variants (in up and down). The up from Locana is in this track 5minutes to hike (bad condition of way), in the other Tambone trail the up uses the street for 150m height.
