The summer travel season is nearly upon us, and we're seeing increased Cartel violence in some popular Mexico destinations. 

Six people were strangled to death and one decapitated in cancun last week.  Another seven were gunned down in March.

Still there are no official travel warnings for Cancun or Cozumel as there are for Veracruz, Acapulco, Tijuana and other places.

“We encourage everyone to be as familiar as possible with the locations they're going to,” the State Department's Clay Adler tells KTRH News.  “We also recommend you let people know where you go and what your itinerary is, and register your travel with the State Department's Smart Traveler Enrollment Program.”

As with any foreign country, Adler says beware of your surroundings.

“Generally stay in the areas where tourists go and you should be fine,” he says.  “If you're getting a bad feeling about something, listen to your instincts and leave that situation.”

“You don't want to wear a lot of jewelry, expensive clothing or carry expensive equipment when you're traveling around not-so-nice neighborhoods,” says Adler.

More than 70,000 people have been killed in drug-related violence in Mexico since 2007.
