Every major city has a place that offers a great vantage point to overlook as far as the eye can see. This is Montreal's. Located in Olympic Stadium, circa 1976, it is nested next to a planetarium and the famous Biodome. While the ride isn't cheap, for first time goers it is worth the money. You take a bi-level gondola up the sloped side of the building, enjoying the views at you ascend.
At the top, there are panoramic views with large windows to better viewing and at it's center, a gift shop. There are no food vendors but if you head down one level, there are seats and tables where you can bring your own snacks and drinks to enjoy. Definitely something not to miss if you're visiting Montreal.
