Many people tend to swim at the Vallarta beaches, but sometimes they are afraid to do so. This is a very well thinking, because there are some risks. Everywhere, where the water is very dark, it becomes very fast very deep, and where are no waves it is the same thing. Close to the rivers the traveler should be very careful, because the water moves very fast towards the ocean and because of the incalculable currents it can become a mayor risk. There are no attacking fishes or sharks around the beaches, I know just about one Fish which lives close to the ground with a lot of prickles. If some one steps over it, it can poison the person. All the areas where many people swim are sure.
