This was for many years my substitute for a gym membership. You should start the climb from the Parc jeanne-mance (Ave. du Parc) side of Mt-Royal. Follow the Olmstead trail, which snakes its way up and offers a consistent grade all the way up. Before the chalet, make sure to turn left to complete the climb to the summit, as there are some spectacular views of the west, north, and east ends of the city.
Once past the famous cross, you are on the downslope. You can then stop and tale a leisurely stroll on the promenade in front of the chalet. From there you have one of the most impressive urban vistas that I have seen.
You can complete the circuit in 30 minutes, but budget an hour for the views and maybe a picnic.
