Holbox Island seems to be the hot spot for viewing and swimming with whale sharks. I can't seem to find any threads related to which tour company is recommended over another. We would also like to hear from fellow forum members that have done this while visiting Playa. Was it a long trip to make from Playa del Carmen?? We will be arriving the end of July which I hear is the correct season. I have always always wanted to swim with a whale shark. We even did 10 days in La Paz years ago on a charter boat just cruising the Sea of Cortez searching for the gentle giants. Any feed back will be greatly appreciated.
