The pier at Playa de los Muertos is the docking point for water taxis to Las Animas, Yelapa and other popular yet hard-to-reach coastal areas south of Puerto Vallarta. There are usually three or four trips throughout the day (six during high season), and most take 30-45 minutes one way.
Please note that the boats usually wait several hours before making the return journey to Puerto Vallarta, so plan on spending a good chunk of time at your destination. If you buy the round-trip ticket (recommended), remember to ask about the return times in advance since another water taxi will not accept that return ticket.
For visitors staying in Nuevo Vallarta, there is regular water-taxi service from below the Paradise Plaza at the pier. Ask for times and rates at the information booth inside the Plaza.
