While you might think that Montreal is the last city in the world you would travel to in order to sit by the pool, you may feel differently after you visit the rooftop of the Ritz-Carlton Montreal. On the rooftop, you’ll feel like you’re swimming through the skyline of Montreal as you do some laps in the saltwater pool. It has the added bonus of being green, as it’s heated with energy reclaimed from the hotel’s kitchens. If that all sounds like too much effort, you can also take in the city views from a seat on the terrace. The hotel also has a well-equipped fitness center open almost around the clock, from 4 a.m. to 2 a.m. each day.
