Safe on time and exhilarating - thanks to driver and boat captain who provided their insight into this remarkable coast - Fantastic and incredibly knowledgeable driver who was passionate about his country and its history. Driver of the boat was equally knowledgeable and provided great commentary.

Great Tour, with Just One Caution - Highly recommend this tour, UNLESS you have back or neck problems. In that case, just be aware: the Zodiac-style watercraft is driven speedily through significant waves for quite a distance, and passengers, particularly near the front, are slammed up and down quite a bit. I didn't mind this at all, in fact I enjoyed it, until one particularly swift, heavy slam-down jarred my neck and it felt a lot like whiplash. It hurt for a few days, and I worried the damage might be longer-lasting. It doesn't seem to be, although I still feel it from time to time. (Pro tip: Sit near the back if you want to be sure this doesn't happen to you. You won't have as good a view, but you'll be safer.) In other news, the caves are gorgeous and the crystal clear water is a spectacular blue-green. There are two stops for swimming (snorkeling if you have your own gear)--though the water was pretty cool, and there didn't seem to be any of the advertised "googles" available, LOL. We four didn't go in, though others did, and I somewhat envied them. Our van driver was friendly, didn't speak much English, but was happy to take the extra time to share a tuna fish lunch with us at the little beachside restaurant on our return from the boat ride. We were picked up at our cruise dock in Cagliari promptly, and returned there well in time to get back on board. It was just us four in the van, which was nice. Since there weren't any tours quite like this offered by our ship, we were very happy to find this one, and at a fraction of the cost of the (much shorter) ship tours.
