The popular trail to Rawson Lake takes you from Upper Kananaskis Lake, past Sarrail Falls, and up switchbacks to a beautiful alpine lake. In summer and early fall, you can hike above the lake for a spectacular birdโs-eye view from Sarrail Ridge.

Rawson Lake Route Description
With lakes, mountain views, and a waterfall in just a few kilometres, Rawson Lake is one of the most popular trails in Kananaskis. Since it isnโt too long or steep, itโs a family favorite that can be hiked all year โ though youโll need microspikes or snowshoes in winter. This beautiful trail is in prime grizzly habitat, so be bear aware and carry bear spray.
The well-marked gravel trail begins at Upper Kananaskis Lake, just past the outhouses, and offers views of the lake and Mount Indefatigable right away. This first 1.2 km section is relatively flat (except for the hill near the start which youโll have to go up on the way back) until the junction which is just past Sarrail Falls/Sarrail Creek bridge. We like stopping for a snack near the falls before the switchbacks start.






A map marks the junction with Rawson Lake Trail. From here, itโs only 2.7 kilometres to the lake, but most of the elevation is in the first half so pace yourself on the switchbacks. As you get closer to the lake, the vegetation gets lusher, narrow โboardwalksโ (split logs) will keep your boots dry in soggy spots, and youโll hear the creek flowing. In early July, look for wildflowers along the trail, and in the meadow en route to Sarrail Ridgeโs summit.
Rawson Lake sits at the foot of Mount Sarrailโs dramatic rock face. If itโs a calm day (or you have a polarizing filter), you can capture perfect reflections in the water. In the summer months (and early fall most years), you can hike around the left (south) side of the lake and see how the water changes color with depth. If youโre lucky, you might see an eagle or fly fisher catch cutthroat trout.
We recommend picnicking on the close (east) side of Rawson Lake since moose and grizzly bears frequent the west side. Return the way you came โ itโs a lot quicker going down the switchbacks!

THERE IS EXTREME AVALANCHE DANGER FROM RAWSON LAKE TO SARRAIL RIDGE. DO NOT ATTEMPT IN WINTER CONDITIONS.
Distance: 5.6 km from Upper Kananaskis Lake parking lot / 1.7 km from Rawson Lake
Elevation gain: 675 m from parking lot / 355 m from Rawson Lake
Difficulty: Difficult due to super steep last kilometre.
Trail type: Unofficial, unmarked
In summer and early fall, you can hike up to Sarrail Ridge from Rawson Lake. Continue around the left side of the lake and follow the trail around the far side of the lake. Your objective is the grassy/treed ridge on the north side of the lake. The unofficial trail along the gully is extremely steep (you will gain 355 metres of elevation over 1 kilometre!), so hiking boots and trekking poles are required. Weโve seen many a tumble and skinned knees and hands on this section (otherโs injuries, not ours)!
There are several picturesque spots along the ridge as you go to the right (east). Watch your step as itโs a long way down from the airy ridge (huge drop-off on the south side). Once youโve had your fill of the spectacular views of Upper and Lower Kananaskis Lake and Mount Indefatigable, return the way you came.



When to Go
Rawson Lake Trail is open year-round, but is prone to closures during berry season when bears are feeding. Check the Alberta Parks โ Peter Lougheed Provincial Park Trail Report before you go. Sarrail Ridge should only be attempted in summer conditions when the trail is dry (it would be super slippery and dangerous when wet due to how steep it is.
IN WINTER, THE TRAIL ENDS AT THE LAKE. DO NOT CROSS THE LAKE โ THERE IS SIGNIFICANT AVALANCHE DANGER!
Know Before You Go
Upper Kananaskis Lake is prime bear territory, so hike in a group, make noise often, and carry bear spray. For tips on staying safe in bear country, see our Bear Safety Tips for Hikers and Backpackers.

Good hiking boots and a windproof/waterproof shell are must-haves. Trekking poles are recommended for the descent, especially if you have a heavy pack.
You should also carry The Ten Essentials including: water, extra food, extra clothes, a headlamp, a GPS/compass and map of the area, bug spray (this one contains 20% icaridin and will repel ticks), sunscreen (this one is safe for babies), and bear spray. Carry bear spray in aย Frontiersman Bear Spray Holster (attaches to your backpack or belt) or Scat Belt.
In winter conditions, โ to Rawson Lake only โ snowshoes or traction devices such as Kahtoola Microspikes (available from Amazon or MEC), or Hillsound Trail Crampons (available at Amazon and Sport Chek) are recommended.ย Reminder: This trail has significant avalanche danger beyond the east side of the lake, so we do not recommend Sarrail Ridge when thereโs lots of snow on surrounding peaks.
