Scuba Diving and Snorkeling

• Cozumel is known for its vibrant coral reefs, and scuba divers can explore the tropical sea creatures at the bottom of the ocean with day trips to Cozumel's reefs. The Palancar Reef is perhaps the most famous off the shore of Cozumel, though scuba divers also explore the San Francisco Reef, which is shallow enough for snorkelers to enjoy. Snorkeling tours are also popular day trip options for docked cruise passengers, and there are several coral reefs for snorkelers to enjoy.
  
  

Guided Beach Tour of Beaches and Jungle

• Cruise ship passengers in Cozumel can explore the city's lush tropical landscape on a guided Jeep tour, which takes visitors through the jungle and across ancient Mayan ruins dating back to 1200 A.D. On select guided beach tours, patrons also get the chance to snorkel some of Cozumel's reefs, and the tours are truly a chance for visitors to go off the beaten path of this tropical paradise.
  
  

All-Inclusive Beach Activities

• Cozumel's main draw is its long stretch of sandy beaches, and cruise ship passengers can opt for a lazy-day excursion and spend the day at an all-inclusive beach, where food, drink, beach chairs and hammocks are all included for one fee. Guests can sip on bottled water, beer, tequila or piña coladas and rent water "toys," such as banana boats or wave runners and spend the day lounging around the Mexican beach.
