There are 4 Trolley routes you can take and all of them are free. These trolleys do not provide tours so there is no tour guide to explain what you see along the way. If you need to sit for a while they are a good place to get where you are going. Just know they will not get you there quickly. Also, there is no schedule of pickup times.
Trolley Routes: Note trolleys are not running at this time. They will be back. Try the Garitas!

Garitas:
Garitas are little golf type carts that travel around Old San Juan. If you see one with no passengers, you can flag it down and the driver will take you where you want to go. They are free to ride.
