“The driver picks up close to the port, The blue water is beautiful. But the boat doesn’t go into the caves. You swim into the caves that are pretty dark. I was disappointed with that. Our boat captain was super nice. Dominic is his name. I think overall it was nice but I really wanted to see bigger caves where you could actually see good. The beach at the end of tour was ok. Pretty small w places to eat & drink. The snorkeling equipment was shared and not sanitized. We didn’t use that.”

“This was a surprisingly and adventurous experience! It was not what my sister and I had envisioned. Yet it turned out to be one of most enjoyable excursions. We are with 10 other guests in a speedboat dingy in the middle of the Adriatic Sea with cruise ships. The sea was extremely choppy to start the day and our captain Stepin who was an accomplished driver navigated the 5-6 feet squalls like we were on a surf board. He was incredible!
