The Bay of Banderas is approximately 17 miles wide (from the north coast to the south coast ) and approx 17 miles from the center of the town of Puerto Vallarta to the Pacific Ocean. Every winter the humpback whales migrate to PV beginning in December and leaving some time in March. The whales return to where they were born, mother whales to deliver their babies inside the Bay where there is less risk of predators.....and for mating. How precious to see the mother whale showing her baby how to breach in the water.....how fascinating to see the mating rituals with the males flapping their fins and breaching, showing off for the ladies. Whales can be seen from the shoreline but most people go out on various types of boats and once they spot the whales, they just anchor close by and enjoy the experience of seeing the whales in their natural habitat. The Bay is wonderful for boating....and fishing. the bigger game fish though are caught just outside the bay in the Pacific. The scenery along the shoreline is breath taking....the water is usually fairly calm and warm.....great for swimming and snorkeling is good in certain areas. One popular area for snorkeling is around Los Arcos....a large rock formation along the south shore. The water is extremely deep there and many varieties of sea life can be found.
