About Grassi Lakes
The Grassi Lakes are on a slope above Canmore, a few kilometres from the centre. The trail is named for Lawrence Grassi, an Italian miner who built much of it in the 1920s. It’s about 4 km round trip, with two options: the easier route along a dirt road and the harder route with stairs and a waterfall viewpoint.
At the top, the two lakes have clear, green-blue water fed by springs. Behind them, limestone cliffs attract climbers, and a narrow canyon rises above. Nearby are pictographs, ancient rock paintings, which should be viewed without touching.
From the trail you can see the Bow Valley, Canmore and the surrounding peaks. The trail is in a protected provincial area. There is no entrance fee.
