With its lively tropical reefs, crystal-clear waters and ancient ruins, Cozumel is ripe for one-of-a-kind adventures. Cruise to Cozumel and head to Chankanaab National Park, where you can snorkel among the colorful reefs and schools of tropical fish that give this island its premier diving status. Or travel back in time on an adventure through the towering Maya ruins of Tulum. When you’re done exploring, unwind with a beachside massage at Playa Mia. From culture savoring to soaking up sunshine, you’ll find a world of adventure waiting for you in Cozumel.

It's rare to find such stunning natural beauty, glass-clear aquamarine seas and vast marine life combined with top-flight visitor services and accommodations, and as a result Cozumel's devotees are legion. Divers sharing stories of lionfish and sharks sit table-to-table with families tanned from a day at the beach club, while Mexican couples spin and step to salsa music in the central plaza. Join the throngs of cruise-ship passengers who shop the countless crafts and jewelry stores along the seaward boulevard downtown.

Take just a few steps off the beaten path and this little island offers big rewards. Deserted, windswept beaches, wild and vibrant natural parks, and 600 miles of coral reef are still yours for the discovering. Just 12 miles off the coast, Cozumel is 33 miles long and 9 miles) wide, making it the country's third-largest island.
