Researched route, Kananaskis

Chester Lake

Kananaskis

A gentle, busy ski trail up through the meadows to a lake below Mount Chester, with avalanche terrain on three sides of it.

Chester Lake sits in a high bowl below Mount Chester and Gusty Peak, in Peter Lougheed Provincial Park near Canmore. It's a ski trail the whole way: 4.3 km and about 340 m of climbing to the west shore, first on an old logging road, then a narrow forest trail through a string of meadows. The trail is gentle, and it's widely described as an easy, busy tour. It's also the common, well documented way to the skiing around the lake. Where you go and what you ski there is your call. The lake itself isn't out of reach of slides, though. It sits at the foot of steep walls, and reports describe slides off Mount Chester running out onto it. We built this route from research and haven't skied it ourselves.

Getting there and parking

The Chester Lake day use area sits on the east side of Highway 742, the Smith-Dorrien Trail, across the road from the Burstall Pass lot. From the Trans-Canada the usual way is south on Highway 40, then Kananaskis Lakes Trail and about 20 km north on 742. From Canmore it's about 40 km south on the same road, past the Nordic Centre. The road is gravel along here and can be rough or icy. Its north end, between Canmore and Mount Engadine Lodge, has been closed for a time for avalanche control, and in 2026 after a rockslide on the hill above Canmore. Those closures are north of the lot, so you can still get there from the south. Check 511 Alberta and Alberta Parks' advisories before you go, and expect no cell service on the road or the route.

You need a Kananaskis Conservation Pass to park. It's tied to your licence plate and bought before you arrive. The lot has outhouses and a trail kiosk, and it fills on busy days. A hiking review describes cars along the side of the highway too. We found no Alberta Parks rule about parking on the shoulder here, so read the signs when you get there.

When we last checked Alberta Parks' trail reports, advisories and annual closures (October 2026), the Chester Lake winter trail was listed as open, and we found no winter closure for it or for Highway 742. Alberta Parks closes the trail every spring, May 1 to June 29, so it can dry out, and lists a group size limit of 35.

The route

The trail leaves from the north end of the lot and crosses Chester Creek on a bridge. A minute past it, the snowshoe trail turns off right. Alberta Parks keeps snowshoers on their own trail, which runs farther south, so the ski trail is for skiers.

About 600 m from the car the old logging road splits in two, and the branches meet again about 1.5 km on. A 2011 trail blog reports Alberta Parks signed them one way that winter: east for going up, west for coming down. We couldn't find that rule on Alberta Parks' current pages, so follow the signs you find. We take the east branch. It's about 1.5 km and 160 m of climbing, the steepest of the whole route, up to about 17 degrees on our data. A 2011 comment on the same blog describes one steep, sunny hill on it that can be rocky early in the season and icy in spring.

Where the branches meet, about 2.1 km from the car at about 2,100 m, a narrower trail carries on into the forest and winds up about 60 m in the next half kilometre. Comments on the 2011 blog describe it as narrow, with steep, tight corners. At about 2.7 km, trip reports have the trail breaking out of the trees into the first of several meadows, with Mount Chester in view. It's nearly level for about 500 m. A last climb through the trees, about 45 m over 600 m, brings you to the big meadow below the lake. Cross it to the west shore at about 2,200 m, 4.3 km from the car. A trip report places an outhouse sign where the ski and snowshoe trails meet, just before the shore.

The skiing

The trail gets you to the lake. The skiing is around it. Where you go and what you ski is up to you. Trip reports and Avalanche Canada reports describe people skiing in three places, and a guide's report from 2017 describes a day touring around the lake on slopes up to about 30 degrees. The angles and aspects below are our own read of the terrain data, not the sources', and slopes are steeper than they appear.

North and northwest of the lake. Up past the Elephant Rocks, a field of big boulders about 100 m above the lake, reports describe gentle, open slopes and scattered trees, with lower Mount Galatea beyond them toward the next lake up the valley. Our read: the ground just north of the lake is low angle, much of it barely a slope, so it's more for getting around than for skiing. Higher up, the slopes below Mount Galatea and Little Galatea steepen to about 27 to 38 degrees, facing southeast. They're sunny, and reports describe crusts on them and quick warming in the afternoon.

Little Chester's north side. The slopes rising south of the meadows. A 2016 trip report saw lots of ski tracks on Little Chester, and an Avalanche Canada report describes a party skiing a northwest slope at treeline there. Our read: mostly 25 to 45 degrees and steeper in places, facing north and northwest, from the meadow's edge up to about 2,550 m. It's avalanche terrain, and the reports have cornices on top.

The far end of the lake. A 2024 report describes heading for the gentler slopes at the lake's far end. Above them the walls and couloirs of Mount Chester and Gusty Peak run 30 to 50 degrees and steeper, and slides off them have reached the lake.

The way out. From the slopes north of the lake, ski back down to the lake or the big meadow and pick up the trail at the west shore. From Little Chester's north side, ski down to the meadows and rejoin the trail where you hit it. From the lake's far end, come back to the west shore. Then follow the trail out: across the big meadow, down through the trees and the first meadows, and down the narrow forest trail to where the old road splits. Take the branch the signs give for the way down (the west one, in 2011). Both lead back to the bridge and the car. Trip reports describe a quick, fun run down. It's busy and narrow, with blind corners, so keep your speed down and call out.

What to think about

Gentle underfoot, steep above the end. On our terrain data no slope of 25 degrees or more comes within 200 m of the trail. From the first meadows on, though, Little Chester's north side rises to the south, 250 to 550 m off the trail, and the lake sits right under the walls of Mount Chester and Gusty Peak. In our runout model, the last few hundred metres of the big meadow and most of the lake are within reach of slides from above. The model is simple, and big slides can run farther than it shows.

Slides that reached the lake. In April 2023 a report found size 3 debris on the lake and size 2.5 at the foot of the Chester Lake couloir's fan. In December 2025 another saw a size 3 in the southernmost couloir run all the way out onto the lake. In January 2024 a small natural slide came down on the fan below Chester Couloir (Avalanche Canada MIN reports, 2023-04-18, 2025-12-14, 2024-01-24).

Little Chester and the col beside it. Slides on Little Chester's north side come up often in the reports. There's a size 2 on its lower part (March 2024), and a size 3 on a north slope at about 2,500 m, likely set off by a cornice (March 2025). A size 2 wind slab set off by a cornice was seen in February 2026 on a day the forecast rated Low in every band, though the report doesn't say how old it was. In November 2022 a skier dropped into a small gully on a steep roll at treeline there and set off a size 1. In March 2023 a cornice fall in the col beside Little Chester ran a size 3 down its full path.

Weak snow near the ground. Reports between the trailhead and the lake describe weak, sugary snow at the bottom of the snowpack in many winters. They found whumpfs and cracking beside Mud Lake by the trailhead (March 2025), a reactive weak layer in the meadows at about 2,200 m (February 2024), and the whole snowpack failing near the ground at the lake on a hot March day (March 2024). In March 2025 a group stopped for lunch by the shore felt a whumpf drop them all, and a shooting crack ran to the creek, where slabs slid down its banks.

The creek below the lake. The outlet creek has steep banks, and slabs have slid into its bed. It's a terrain trap close to where people stop.

Warm days. On a sunny March day with 14 degrees at the car, a report saw big natural slides on Mount Chester and Gusty Peak, some size 3 or bigger. The south and southwest slopes north of the lake warm first.

A busy, narrow trail. It's one of the most used trails in Kananaskis. Skiers come down the narrow upper trail fast, and reports describe a steep pitch that can be icy. Snowshoers have their own trail.

What the reports show. Most slides in the Avalanche Canada reports near this line were on the north and northwest slopes of Little Chester and Mount Chester, in the couloirs and walls around the lake, and in the col between them, at treeline and above. They were wind slabs, cornice falls, and slabs on the weak snow near the ground, with bigger slides in warm spring sun. Most released on their own, and a few were set off by people. Some were seen on days rated Moderate, and one on a day rated Low. Reports follow where people go, and this is a busy place, so a quiet record somewhere else wouldn't mean quiet slopes.

Two readings. A ski touring page says there's no avalanche terrain short of the lake, and snowshoe guides call the trail free of avalanche danger. The trail is gentle, which is what they describe. The terrain and the reports put the lake and the meadow before it within reach of slides from the walls above. We go with the terrain and the reports.

What would turn you around

On the way in: whumpfs or cracking, even on the flat, fresh slides on Little Chester or the walls above the lake, or a forecast of persistent or deep slabs with new snow, wind or warming.

At the lake and on the slopes around it: loaded cornices on Little Chester or the col, fresh wind slabs, sun on the south and southwest slopes after midday, or fresh debris on the lake. The signs count the whole way, on the trail, at the lake and in your runs.

It's out and back on one trail, so turning around anywhere only costs you the lake.

Whether to go is your call on the day. Read the forecast and decide from what you find.

Where this plan could be wrong

What it asks of you

An easy trail to a lake ringed by avalanche terrain. About 8.5 km and 340 m of climbing, on skis the whole way, with a quick run back down a busy trail. One trip report allows about 3 hr on foot for the round trip with the Elephant Rocks. The trail needs basic ski skills. Once you leave it for the slopes around the lake you're in avalanche terrain, and slides from above have reached the lake itself. For that we'd want avalanche training, a transceiver, probe and shovel, and partners who know how to use them.

What we can't tell you yet. How it skis on the day, how tracked out the slopes are, and how long it takes you. The dashboard's estimate uses your own pace.
