Cozumel is the largest island in the Mexican Caribbean and the region's most popular cruise port. Known as a diver's paradise, Cozumel is considered safe for visitors, since most of the recent drug-related violence has been in cities along the border. Resort areas like Cozumel are generally safe, according to officials, as long as tourists follow basic safety tips.
Staying Safe
Crime is low in Cozumel due to it being an island community dependent on tourism. As with anywhere with large groups of tourists it is always wise to keep money and valuables safe from pickpockets and petty thieves, but violent crime is extremely rare. Some biting insects such as mosquitoes and sand flies can be an annoyance, but do not carry diseases such as malaria. They can easily be avoided by using repellent and wearing long sleeves and pants at dawn and dusk and using air conditioning, fans or insect nets to sleep.
Tourists in Cozumel are advised refrain from swimming in areas where red and black flags are posted these signify dangerous currents. Drowning and near-drowning incidents have been reported on the east coast of Cozumel, particularly in the Playa San Martin-Chen Rio area." As well use only licensed and registered taxis, which can be called on request by staff at restaurants, nightclubs and hotels . Also be careful about scooter rental and scooter safety in general. Cozumel has experienced a rapid rise in scooter-related accidents.
Staying Healthy
Health officials suggest that tourists in Mexico stick to bottled water to avoid illness and to wash and peel any produce purchased at street markets. No inoculations are required for entering Mexico, but updating tetanus vaccines and getting swine flu shots are a good idea, especially if tourists plan to be very physically active.
