Peter Lougheed Provincial Park, AB
A long, unsigned branch to a lake beneath Mount Rae.
Overview
Rae Lake Trail is a 17.2 km (10.7 mi) out-and-back from Elbow Pass Day-use Area, following the Elbow Lake approach before an unsigned branch reaches Rae Lake below Mount Rae. Plan for 5 to 7 hours and about 432 m of cumulative climbing. It is a long, moderate day; I’d choose it when Rae Lake is the goal and you’re comfortable watching for cairns. Elbow Lake is the much shorter walk from the same trailhead.

Trail guide
Follow the trail along Elbow Lake’s west shore, cross a small creeklet on a log, then stay left onto a road that climbs into a meadow. Mountain bikes use this section too. About 4.3 km from the start, a view opens over Piper Creek Canyon. Stones mark a short optional side trip to Edworthy Falls.
Roughly a kilometre beyond the canyon view, you’ll reach cairns for Piper Pass. The Rae Lake cairn is about 50 paces farther on the right as you head northeast. That turn is unsigned; once you’re on the boot-beaten branch, the path is described as clear. Missing the cairn is the main route-finding risk.
Rae Lake sits below the north end of Mount Rae, east of Tombstone Pass. Larches grow near the lake and turn color in fall. The route starts at the Elbow Lake trailhead and continues into adjoining Elbow-Sheep Wildland Provincial Park, so expect a less formal route than a signed day-use walk.
Use the Elbow Pass Day-use Area on Highway 40, the same access as Elbow Lake. The parking lot can fill on busy weekends. A Kananaskis Conservation Pass is required for vehicles parked here, and pets must stay leashed to no more than 2 m. Highway 40 closes seasonally; check current road access before setting out.
