Find your way to Puerto Aventuras Marina in Riviera Maya in the morning to meet your 82-foot (25-meter) catamaran, 'Raiatea.' The staff will welcome you aboard and you'll depart for the 80-mile (130-km) trip to Tulum. Watch for dolphins and other ocean life as you relax on the open sun deck, cruising over the Caribbean's turquoise waters.
The next stop is snorkeling in Tulum. The Raiatea will moor near the coral reef so you can jump right in wearing the provided snorkel, mask and fins. Swim amongst schools of tropical fish and marvel at the different varieties of coral.
Climb back onto the catamaran and sit down for a buffet lunch, including unlimited drinks. Then disembark on Playa Zazil Kin for some free time to relax and beachcomb before your tour of the ruins.
Follow your guide through the well-preserved ruins of Tulum that date from the 13th century, when it was an essential trading port. Learn about the historical and cultural importance of the site while exploring on foot.
After your tour of the ruins at Tulum, head back to your Riviera Maya or Cancun hotel by van or by bus (own expense).
