We selected the 4 hour whale watching tour provided by Vallarta Adventures and were rewarded with a Fantastic tour. We were on a large Zodiac inflatable boat with a very compentent crew including a marine biologist (Nikki) She was completely bi-lingiual and explained about the whales habits and where to best view them. She was passionate about (her) whales and voiced her opinion when another boat crowded the whales. We saw many that day, singles. mothers & calves an a breeding pod of 8 together.A great day, a great trip by a very professional and eco-friendly crew.
