Explore Cozumel History

• Head to the Museo de la Isla Cozumel, the Museum of the Island, in downtown San Miguel, the island's main town. Housed in a former luxury hotel, the museum features several exhibits detailing the history of the island, its culture and ecosystem. See replicas of colonial-era ships, ancient Mayan artifacts and an exhibit on the wildlife that lives on the island. Step inside the historic San Miguel Church to take in its beauty and see an ivory statue of the archangel Saint Michael, believed to be hundreds of years old. You also can stroll the streets of San Miguel under an umbrella, checking out the historic Spanish colonial-style buildings and shops.

Relax, Mayan-Style

• Put on a plush robe and enjoy the spa at your hotel or one nearby. Top full-service spas in Cozumel include the Mandara Spa at the Presidente Intercontinental Cozumel and the Awe Spa at Cozumel Palace. Enjoy classic spa treatments such as deep tissue massage, herbal wraps and body scrubs, and take advantage of special treatments you'll find in only Cozumel or Mexico. The Mandara Spa features the Mayan Temazcal treatment, a steam house purification ritual led by a Mayan shaman, requiring you to breathe in medicinal herbs that are supposed to flush out toxins in your body.

Get Your Grub On

• Indulge in the best Yucatan Peninsula-style Mexican food you can find. Grab your umbrella and get off the beaten path by strolling the neighborhoods to find small eateries where the locals eat. You'll find the most authentic local eats and typically at much cheaper prices away from the hotels. Expect to find menu options such as cochinita pibil, a marinated, slow-cooked suckling pig, and huevos motulenos, a breakfast option consisting of fried eggs, tortillas and black beans and smothered in tomato sauce. Sign up for a food tour, visiting a traditional Mexican market with a guide and sampling local food and drinks at various restaurants.

Play in the Rain

• Unless there's lightning and thunder, there's no reason you can't still enjoy your favorite outdoor vacation activities. If it's hot and muggy with light rain, go ahead take a dip in your hotel's pool. You can even go snorkeling -- you're going to wet anyway. Gather a group of others not afraid of the rain for a sand volleyball game. You'll get more sand stuck to you, but you can always rinse it off with a quick dip in the ocean. In the Caribbean, rain is often sporadic and brief, even in the rainy season. There's a good chance you'll be able to lie out in the sun to dry before long.
