Once aboard the boat, you have the choice to sit in the shaded, covered section, where you can look through the glass bottom of the boat, or on the deck to have a taste of the fresh sea air. A buffet lunch or Spanish snacks is included in the price. About halfway through the tour, the boat stops in a bay, allowing the passengers to plop off the back of the boat into the clear waters for a dip or a snorkel. The snorkeling was excellent since the waters were crystal clean, and I spotted some exotic looking fish! An English commentary is given at intervals during the tour to explain the passing sights. I'd recommend taking a camera as the sights can be breath-taking, and if you're lucky you might snap a dolphin or whale!
