There's a few ways to get to this park....easiest if you are taking public transportation:
- via the metro, get off at Station Mont-Royal on the orange line
- go to the bus stop behind the metro station on Rue Rivard and get on bus 11 toward Montagne. This bus will go up the mountain saving you a very long walk up unless you plan on biking up there.
You can still walk around the many trails once you get off the bus stop there that's near a very large parking area. You can head up a trail that will take you to the top of the peak where you will get a very nice panoramic view of Montreal. Walking up and looking around will be less than an hour unless you want to spend more time around the trails. I didn't have that luxury so we just did this part and left even though there was lots more to see.
Then once you're done the walk take the bus 11 back down the mountain to St. Laurent Blvd. Get off at that street and walk to 3895 St. Laurent Blvd to Schwartz's for short wait and a great Montreal smoked meat sandwich. Perfect way to experience two great Montreal spots!
