Start in Villach, follow the Alpe Adria corridor through Tarvisio and Venzone, pause in Udine for a glorious piazza, then drift past Aquileia’s mosaics toward Grado. Use trains to shorten hours if heat rises, and toast arrival with lagoon light reflecting softly on spokes.
Begin near Dobbiaco or Cortina on the converted path toward Calalzo, step by train to Belluno and Treviso, then meander east along river trails. Finish in Trieste with cliff views and seafood. Rest whenever vistas insist, and let rail links stitch generous shortcuts as needed.
Trace waterfront promenades from Trieste to Koper, explore Izola and Piran, then continue toward Portorož and the Parenzana’s inland curves to Grožnjan and Motovun. Rejoin the coast near Poreč. Mix beach swims with hilltop sunsets, lean on local trains, and collect stamps, smiles, and salt.
