2. Leg 2 · Villach Hbf → Jesenice

   approx 1 h

   Continues to Ljubljana. There is no passenger rail into Bovec or Trenta: the last leg is a bus, always.

   approx 0 h 45

   Soča valley shuttle, lines V4 / SONEP4

   Daily 1 – 25 Jun and 1 – 25 Sep; weekends and public holidays on the SONEP4 pattern. Outside roughly June to September there is no bus over the pass at all.

One rail connection from Paris to Vienna. We verify those legs for your dates in the Dossier.

What closes, and when

• The Vršič pass is a seasonal road, typically closed from November to late April or early May on snow and avalanche risk. There is no fixed date; promet.si carries live status.
• The Bovec – Soča source – Vršič – Kranjska Gora shuttle runs 1 – 25 Jun and 1 – 25 Sep. Verify July and August frequency on the valley's own mobility page.
• With Vršič shut and the shuttle stopped, the valley is reachable only from the Tolmin and Kobarid end in winter.

Thin timetable

• No train reaches Bovec or Trenta. Budget the bus leg properly; it is three hours, not an hour.
• If you are going for the Soča source without a car, your dates have to sit inside the shuttle windows.
• Vršič closes in November and does not reopen on a schedule. Do not plan a crossing in the shoulder without checking promet.si the same week.

Local rules

• Trenta is a handful of farms, not a resort. Park nothing on the verges and take the shuttle if it is running.
• The war remains are graves as much as heritage. Nothing is a souvenir here.
• The Julian Alps Card gives free valley transport to guests. Ask your host for it on arrival; it removes the reason to drive.
