One tip that may prove to be financially valuable to you is the following. When you get a ticket from a major motorway toll booth, exits from the motorway on slip roads are free if you show it to the cashier or scan it in the ticket reader.
The ticket from this tollgate gives you the right to one passage during a period of 12 hours through the slip-road toll gates between (and including) Bulnes and Mininco |
If you don't have your ticket you can expect to pay 500 CLP, which isn't too much so don't worry if you lose your ticket. Click here for a conversion
