If there is one water activity that you should do atleast once in your life time, you need to swim with giant whale sharks. These docile fish aggregate just off of Isla Mujares every year from June to Sept. Blue H2o Cozumel has been doing whale shark tours for 11 years and are experts. If you are staying in Cozumel, Tulum, Playa Del Carmen or Cancun we can definately make this a tour for you to remember. Plan and book now.
