Crossing the Island of Elba by MTB along cycle paths (S2 maximum S3, see below). Tested and approved by Elba MTB. The route avoids the wildest trails on the island, typical of the GTE (Grande Traversata Elbana) trekking version, but still requires experience in single track riding.
The GTE version is not suitable for Bike use: too many stretches of uphill portage (even in the case of e-bikes and expert bikers) and difficult descents, which often do not have the flow characteristics that a single-trail must have to be appreciated by the bike user.
