Due to the fluctuating exchange rate, a four star review of a park in Canada is roughly equivalent to a five star review of a park in the US.
Nah, I'm kidding. I reserve five stars only for Central Park and Prospect Park (also Olmstead parks). But Mont Royal Park is pretty awesome. There is plenty to see all over the mountain and the views of Montreal are terrific.
I love approaching it from Rue Rachel because the angel statue there (Sir George Etienne Carter) is pretty impressive. You really get a sense of the scale of the place that you don't get from approaching it from the south, in my opinion. There are so many paths that you can discover a variety of things as you climb toward the summit. I once met a friendly horse not too far from the giant cross.
This is a real gem and it seems that Monteralers (Montreal-ites?) really appreciate this place. When I've been there it has been spotless and well tended. It's very cool. Or as they say in Montreal, tres cool.
