Bike parking at Jazz Festival
There are two bike specific parking lots at the jazz festival, one at the east side of the site and one at the west side of the site.
You can see the site map here (link). You may have to drag the map left or right to see the bike-parking icon.
The Jazz Festival is a great activity, free to visit, free to park your bike, just be careful on your bike when going to or coming home from the site.
Note: the de Maisonneuve bike path through the site is open daytime only.
