Boom Lake on Skis – A Fun Winter Outing
Boom Lake in Banff National Park is a popular destination in both summer and winter. I don’t find hiking the Boom Lake trail in summer as interesting as it’s primarily in the trees. But in the winter, the Boom Lake trail is a cross-country skier’s delight.
The trees muffle the sound and hold the snow. And they keep the wind at bay, so it’s not so cold. Located in Banff National Park near the boundary of Kootenay National Park, it’s an easy 5 kilometre ski into Boom Lake. The total elevation gain is only 180 metres (590 feet).

Boom Lake cross-country skiing description
For the first 1.5 km, the trail climbs at a moderate rate. Then it levels out and merely rolls up one small hill and down another. The final run to the lake is all downhill; it’s fun but the trail wiggles and there are some tight corners which might not appeal to everyone.
The area is in a real snow belt, so you may have to break trail if you’re the first one out. That can zap your energy in short order so take turns if you’re with others.


Boom Lake first impressions – what a place!
Humans look puny next to the cliffs rising 600 metres up from the lake. We did ski on the lake for some distance – but backed off when we hit some slushy areas.
A lot of people call it quits when they reach the lake but if conditions are good then you can ski for at least a kilometre in either direction on the lake itself. Out in the middle there seemed to be some surface water over the ice so we backed off and stuck to the shore. There are several frozen waterfalls around the lake. The intense blue of the ice is truly beautiful.


Beware of hazards!
Be aware of your surroundings on the lake. There are several avalanche paths that come right down to the shore. This is Class 2 or challenging terrain. You & your entire party should be carrying full avalanche gear & have avalanche skills training and SOS devices if you go forward. Unless you’re an expert in reading the snow pack, play it safe.





All told it took us about four hours to ski in and out from Boom Lake. That included a lunch break and several extra kilometres of skiing on the lake itself.



Where to park
Parking is excellent. Look for the large signed parking lot on the north side of Highway 93, just 6 km from Castle Junction and only a few minutes away from Storm Mountain Lodge. There are no services but there are washrooms.
Where to stay near Boom Lake
While you could stay at nearby Storm Mountain Lodge, there are lots of other options in Lake Louise or at Castle Junction. It’s a 25-minute drive from Lake Louise Village.
For good value for money stay at the Lake Louise Hostel. The Mountaineer Lodge is a stone’s throw from the village – and offers comfortable rooms.
For a splurge stay at the Fairmont Chateau Lake Louise.
In Castle Junction, check out Castle Mountain Chalets.

The forest looks amazing. I’m doing it tomorrow!
My jaw dropped at your pictures of Boom Lake! Why is called that?? Scrolling back up to look at those photos again 🙂
@Mike Boom was nice but nearby Chickadee Valley even better. It’s named after a naturally occurring log boom.
I thought it was named ( I’ve heard it in the spring ) for the BOOM of the constant avalanches echoing in the valley . That happen in the spring time .
@Paul You may be correct. You certainly have to be aware of your location and avoid some of the steep avalanche prone slopes.
I think I will give the avalanche path a wide berth as I do not know the proper Nordic technique for skiing avalanches. Holy cow that snow on the trees is amazing.
@Ted I have done avalanche courses but I think there is more art than science to predicting when they will run. I definitely avoided being near the bottom of any path – and if I was, we went one at a time – very quickly.
That frozen waterfall is amazing!!
@Patti And there were even bigger ones across the lake.
