Public transportation is an inexpensive way to get around, not to mention a great way to see Puerto Vallarta. They are very efficient and come by very frequently. At 6.5 pesos to go anywhere in Puerto Vallarta, I highly recommend taking some time to figure out the system.
Bus stops do have signs posted and are blue and white but also you’ll be able to tell its a stop as there will be a group of people waiting as well. On the front or side of a bus there will be a list of places that bus is going to like Walmart or Costco for instance.
When you see the bus you want to take, flag it down and don’t be shy. Make sure to have small bills or exact change only. The driver does have some change but it’s just easier if you have the exact amount. He will give you a little ticket that you can use to transfer or in case a security person comes along to make sure you paid as its your receipt too.
Now hang on for dear life! Haha. You’re going on an adventure now!
