Grassi Knob is a ridge that rises from the east slopes of Lawrence Grassi and overlooks the town of Canmore and Three Sisters. It's a cool hike which isn't that well known.

The trail starts at the Three Sisters Village and while it's under 9 km round trip, the elevation is around 800 meters, making the way up really steep. The views of Three Sisters are so beautiful though and it's a quieter alternative to other trails near Canmore.
