This is such a large park and not only does it offer green grass for picnickers, dog walkers and sun worshipers, it also provides terrain for those who want a hike, run or bike ride.
We decided to walk the park and didn't really plan on walking to the top, but the more we walked, the more we reasoned that we were just getting closer to the top so we finally decided to just make that our goal.
The walk to the top took us about an hour. The terrain is gravel and it's quite shady. The way to the top is by long switchbacks up the mountain and then a long set of stairs to the top. Once you reach the top, you're rewarded with a view of Montreal (on a clear day) and there's plenty of steps and chairs to sit and rest.
For our way down, we saw a short cut which basically when straight down the mountain via steps. It spit us out behind McGill University so if you don't want to take the long route up (what we did), you can take the short cut (the stairs) and just head straight up to the lookout area.
A fabulous park and nice escape from the city.
