Rawson Lake Trail

From the day-use area, follow the Upper Lake Trail beside the water for about 1.1 km. This is the easier warm-up, with small rises and dips along the shore. At Sarrail Creek, a bridge crosses beside the falls; shortly afterward, follow the signed Rawson Lake branch away from the lakeshore. A short boardwalk is part of the route. The fork matters: stay on the branch for Rawson Lake rather than continuing around Upper Kananaskis Lake.

After the junction, the walk changes character. The trail climbs steadily through subalpine forest for roughly 2 km, gaining most of the route's 320 m. The tread is unpaved but well defined, and the way is straightforward to follow; the effort comes from holding the uphill pace. Some hikers find the sustained grade tiring, especially on the descent. Take a breather when you need one, and consider poles if steep downhill walking bothers your knees. Near the end, the grade eases before the trees open into the lake basin.

Rawson Lake sits in a hanging valley of alpine meadow and mountain peaks, below the cliffs of Mount Sarrail and its northern outlier. The lake is the payoff for the climb; you do not need to continue farther to make this a worthwhile walk. For a photo, include a strip of water in the foreground and the cliff wall beyond it, so the mountain setting reads as a basin rather than a tight rock portrait. The marked Rawson Lake trail ends at the shore. Sarrail Ridge continues beyond as a separate, more demanding route and is not included in this distance.

Park at Upper Lake Day Use Area, the signed access for both the Rawson Lake and Upper Lake trails. A Kananaskis Conservation Pass is required for vehicles parked there. The day-use area has pit toilets and a water pump; no food vendor or reliable refill point is documented along the hike, so bring food and enough water for the climb and return.
