Start your snorkeling excursion with convenient pickup from your Cancun hotel. Be sure to bring a swimsuit, sunglasses, biodegradable sunscreen, dry clothes, and a towel. When you get to the dive shop, you'll be outfitted with snorkeling equipment, including special snorkeling life vest, mask, snorkel fins and a weighted belt.
Board the dive boat and cruise out to the first of your three stops, on a virgin reef. Dive in and swim in the same direction as the current, which makes for easy snorkeling. See larger and different fish who frequent deeper waters than you would at shallower reefs, including black grouper, yellow snapper and barracuda. Keep your eye out for stingrays and turtles. Stop at a shipwreck, surrounded by crystal clear water and stretches of white sand, as the finale to your trip.
Return to land, where you can use the showers before returning to your hotel for drop-off.
