Great experience, this was a small private tour, the tour guide was very knowledgeable and explained the history of Croatia and Slovenia, he went out of his way to view an extra attraction which was very enjoyable. I highly recommend booking with this tour guide.

Toda la actividad nos encantó, tanto el castillo como las cuevas nos parecieron alucinantes. Luego tuvimos tiempo para almorzar y recorrer la capital de Eslovenia (Liubliana), vale la pena verla. La guía, Tania, resultó increíble, llegó puntual, estuvo todo el día a nuestra disposición, amable, amorosa, contestando cada una de nuestras preguntas e incluso asesorándonos con algunas cuestiones que debíamos resolver para nuestro regreso. Actividad totalmente recomendable.
