An evening-start point-to-point across Croatia's Istrian peninsula, from the ancient town of Labin over Mt Učka with views of the Kvarner Gulf, down to Buzet, then through inland medieval towns such as Motovun to Umag on the west coast. Expect rocky technical terrain, deep forest, an old railway line and muddy valleys.
