A light sweater and a rain jacket also come in handy during the winter and rainy seasons. Water shoes come in handy wherever the beach is rocky, while sneakers and bug repellent are musts for the Maya ruins. Beach buffs should bring two or even three swimsuits, plus snorkel gear if you have it. Bring to Cancún and Cozumel what you would to any beach or tropical destination: light cotton clothing, hat, sunscreen, sunglasses, flip-flops, and so forth.
