Every fall, Alberta’s mountain landscapes are transformed as the province’s larch trees turn brilliant shades of gold before shedding their needles for winter. For a short period each year, the trees add bright pops of yellow to the mountain scenery, making this a popular time to explore the Rockies.
But larch season typically lasts just a few weeks, so timing can make all the difference if you want to catch these trees at their peak.
If you’re hoping to catch the larches while they’re at their brightest, there are a few things to keep in mind when planning your trip.
From when the season usually starts to how to spot a larch and where to find them around Alberta, here’s what to know before heading out.
Larch season is a relatively short window, with the trees changing colour as fall arrives. According to Alberta Parks, the prime window for seeing alpine larches turn golden typically runs from mid-September to early October, though timing can vary year to year depending on conditions.
That means there isn’t one specific weekend when every larch in Alberta will suddenly be bright yellow. Elevation, weather and location can all affect when the trees change, so if you’re planning a trip around the season, it’s worth checking recent conditions before you go.
Larches look like other coniferous trees for much of the year, but there’s one major difference: they lose their needles. According to Alberta Parks, alpine larches, known scientifically as Larix lyallii, have soft needles that turn yellow in autumn before falling off for the winter.
You don’t need to be a tree expert to spot one once you know what you’re looking for.
The easiest giveaway is the needles. Unlike spruce or fir trees, larch needles grow in soft clusters and turn yellow in the fall. Eventually, those needles drop, leaving the tree completely bare during winter.
According to Alberta Parks, many popular larch hikes in Alberta’s provincial parks are in Kananaskis Country, although alpine larches also occur elsewhere in Alberta. Some of those locations are less well-known or tucked deeper into forested areas.
Here are some of the spots worth adding to your list:
Fall in the mountains can look very different from fall in the city, so don’t assume you’ll get the same weather once you’ve reached the trailhead.
Come prepared with layers, proper footwear, snacks, water and bear spray before heading out for a hike. And if you’re hiking to a higher elevation, bring a waterproof or windproof layer, gloves, and a toque. Check the weather before you leave; Parks Canada notes that temperatures in Banff and surrounding areas can drop as the elevation increases.
Larch season also lines up with rutting season, when male elk, moose, and other species can become territorial. According to Alberta Parks, the rut generally runs from mid-September through the end of October, and behaviour changes can make these animals more aggressive.
If you happen to run into one of these animals while you’re hiking, it’s advised that you stay 30 metres away, keep dogs on a leash and detour around them rather than trying to walk right past. And if you’re driving through the mountains, the same rule applies from inside your vehicle.
Fall is an especially active time for bears in Alberta, as they prepare for winter by eating and drinking as much as possible. According to Alberta Parks, this can make bears less observant of their surroundings, so it’s important to stay bear aware.
Carrying bear spray is one of the easiest ways to be prepared. Alberta Parks recommends keeping bear spray somewhere you can reach quickly and making sure you know how to use it before you need it.
If you happen to come across a bear, give it plenty of space and never approach it for a photo. Keep your group together, make lots of noise and slowly move away from the area.
