Although Puerto Vallarta is an incredible city and you may find it difficult to leave, you might enjoy one of these great side trips. All can be done in a day, although you may want to spend the night.
Bucerias, Sayulita and San Francisco, to the north, are an easy drive (less than an hour) and the trip may even be made by way of taxi. The villages of Las Animas, Quimixto and Yelapa to the south, are inaccessible by car, you must go by boat.
Tours, snorkeling cruises and booze cruises to the southern villages are readily available from the many tour operators. You can also hire pangas to take you there from almost any beach in Puerto Vallarta.
