You'll have already seen the indescribable blue of Peyto Lake in a thousand publicity shots, but there's nothing like gazing at the real thing; especially since the viewing point for this lake is from a lofty vantage point several hundred feet above the water. The lake is best visited in early morning, between the time the sun first illuminates the water and the first tour bus arrives.
From the bottom of the lake parking lot, follow a paved trail for 15 minutes up a steady gradual incline to the wooden platform overlooking the lake. From here you can continue up the paved trail, keeping right along the edge of the ridge. At the junction of three trails, follow the middle trail until you reach an unmarked dirt road; if you continue down it for about 2.5km you'll find yourself in a serene rocky bowl with a stream running through the center.
