In my last trip to Europe in December 2015/January 2016, I wanted to visit Slovenia from Trieste, Italy, and I started looking for day tours. One of the agencies I found was Slovenia 4 Seasons, which offered a really good deal for a customized tour for visiting Postojna Caves, Predjama Castle, and Lake Bled. At first, I was in doubt if I should hire them or not, because the price was more than 100 EUR lower than the most expensive agency, but I took my chances. What I can say is that it was a really great tour and Andrej Vatovec, one of the owners, was a fantastic guide. He is very kind, arrived at the hotel exactly at the agreed time, and made my tour a really pleasant one. I totally recommend Slovenia 4 Seasons!!!
