My husband and I stopped in Cagliari on a cruise. Looking for things to do, I ran across this tour. I almost cancelled it and I am so glad I did not. It was truly one of the highlights of the cruise. The site was one of my favorite sites on my 2.5 week trip in Europe. You literally get to crawl through 5,000 year old ruins that are extremely well preserved. Our guide was excellent--very knowledgeable and friendly. He even brought us homemade cookies to welcome us to the island. A must see if in Sardinia.
