If you want a unique, relaxing, educational and exciting adventure then Panterra's trip to the Sea of Cortez is what you want. The experience we had swimming beside the huge whale sharks and tagging giant sea turtles was unforgetable. Lela and Stasia made our family trip not only enjoyable but also educational. They are both extremely knowledgeable and passionate about the area and the marine life. We came away with an appreciation of the Mexican culture as well as for the beauty of the area and it's wildlife. This was a trip of a lifetime and we highly recommend Panterra Adventures. This is a must do for your bucket list.
