You can park your car at one of the parking lots in the Byward market area and then walk to the Hill. You may have to pay $15 or more for the day though. Or you can park at OC transpo park and ride and then take the bus. How to take the bus, it depends on where you live. You can call OC transpo to find out your routes.
