There are dolphins and manta rays as well as countless other species living in the bay. Scientists from the University Center of the Coast, a campus of the University of Guadalajara, have discovered various types and colors of coral as well as tropical fish. The calm waves make for pleasant swimming and efficient treatment plants ensure the cleanliness of the water. Surfers like to test their skills against the waves just outside the confines of the bay in Sayulito and San Francisco, north of Puerto Vallarta in the State of Nayarit. There are numerous tennis courts with constant tournaments during the winter months.
Most courts have tennis clinics as well as tournaments.
The professional quality courts at the Hotel Continental Plaza , formerly the John Newcombe Tennis Club, are the site of annual classifying tournaments for world ranking that attract many players who may become the stars of tomorrow. The courts found in the various hotels throughout Puerto Vallarta have a variety of surfaces, including grass and clay. Many hotels have lighted courts, also.
