Suggested rhythm

A circular day, not an out-and-back

  1. Borgo Botol

    Begin early for the motorway drive across Friuli.

  2. Redipuglia Memorial

    Walk through Italy’s largest First World War memorial and consider the battlefield landscape around Monte Sei Busi.

  3. Duino Castle

    Tour the castle, gardens and tower above the Adriatic, with time for the old-castle view.

  4. Rilke Trail

    Walk the panoramic cliff path towards Sistiana, then pause for a Karst lunch.

  5. Grotta Gigante

    Join a reserved guided visit into the immense central chamber; bring a jacket and suitable shoes.

  6. Borgo Botol

    Return to Borgo Botol after crossing the Trieste Karst.

Lunch recommendation

Make lunch part of the route

Lunch on the Karst: reserve an osmiza or a small local restaurant for cured meats, cheese, jota and Terrano wine before the cave visit.

Restaurant and attraction openings change seasonally. Reserve ahead and confirm on the day.
