While Puerto Vallarta is a walkable city, travelers may want to consider taking a taxi or bus for longer distances. Taxis are affordable, but be sure to negotiate a price beforehand. Buses are even cheaper, with a fare of around $1 per ride. For the day trip to San Sebastian del Oeste, a rental car may be necessary.
If you have more time, consider adding a day trip to the Marietas Islands for snorkeling and beach time. If you have less time, consider skipping the day trip to San Sebastian del Oeste.
