You can’t fall if you don’t climb. But there is no joy in living your whole life on the ground.
Hiking around Lake Louise is worth your time.
If you want an easy stroll you can start with the lake view trail.
For those who don’t have that much time you can go try the Fairview Lookout. An half an hour climb to a magnificent lookout view over the Lake and the Fairmont (all year). This trail starts close to the canoe docks, on your left from the lake with the Fairmont behind you.
The more extensive hikes are the ‘Plain of Six Glaciers’ , ‘The Big Beehive’ and the trail to ‘Lake Agnes‘. All these hikes are accessible during summer only and start on the right side of the lake (if you are facing the lake with the Fairmont behind you). Make sure you stop at the teahouses for a nice little break.
