We had a nice relaxing morning, and Xanadu arranged an afternoon snorkeling trip with a local dive/snorkel operator to the Mexico Rocks, a site that is on the northern section of the caye. The boat came right to the Xanadu pier, picked us up as well as some other travelers participating in the excursion, and continued 25 minutes out to the reef. The seas were calm, but the sun was really hot. Sunblock is a must for this trip, and I recommend wearing a hat and shirt, at least for the boat ride. This was the first snorkeling trip that we did in Belize, and we had a great time. The area where we were snorkeling had very interesting coral reef habitat for tropical fish. The highlight for me was seeing a group of squids that swam in a perfectly synchronized line. As we approached, they seemed to move in unison, turning and changing speed, but never changing their formation. We snorkeled at the first site for about 30 minutes and then hopped back in the boat and traveled to another area to get back in the water for 45 minutes. Carrie was glad she brought a long sleeve, synthetic shirt that she could wear since she did get a little chilled being in the water so long. After snorkeling, we were dropped off at Xanadu, and we then headed out to enjoy another dinner at a small restaurant next to Xanadu that had good lobster.
