Every fall the Canadian Rockies transform into a golden wonderland. The alpine larches, a rare type of tree that loses its needles each year, turn bright yellow for a short window in September and October. One of the best places to see them is the Larch Valley and Sentinel Pass trail in Banff National Park.
This hike starts at Moraine Lake and takes you through dense forest, into a valley surrounded by glowing larches, and higher still to Sentinel Pass for jaw-dropping mountain views. It is one of the most famous larch hikes in Alberta, and for good reason.
What Makes Larches Special
Unlike evergreens, alpine larches are deciduous conifers. Their needles shift from green to fiery gold each fall before dropping for the winter. The colour change lasts only a couple of weeks, which is why September in Banff is often called “larch season.”

Trail Overview: Larch Valley and Sentinel Pass
-
Trailhead: Moraine Lake, near the canoe docks
-
Distance: 9 km return to Larch Valley, 11 km return if you include Sentinel Pass
-
Elevation Gain: 550 m to Larch Valley, 750 m to Sentinel Pass
-
Time Required: 3 to 5 hours for the valley, 4 to 6 hours for the full route
-
Difficulty: Moderate, with some steep switchbacks and a rocky climb past Minnestimma Lakes
The first section climbs steadily through the trees before opening up into Larch Valley, where you will find meadows full of golden larches surrounded by the Valley of the Ten Peaks. If you continue past the Minnestimma Lakes to Sentinel Pass, you’ll gain a higher perspective of both Larch Valley and Paradise Valley. The views are dramatic and well worth the extra effort if conditions allow.
Best Time to Hike
The larches usually peak in colour from mid-September to early October. Weather can vary quickly, so check the official Parks Canada trail report before heading out.
Earlier in the summer, the trail is still worth hiking for wildflowers and alpine views, but you will not see the golden trees.
Getting to the Trailhead
Private vehicles are no longer allowed on Moraine Lake Road, with a few exceptions. Only guests of Moraine Lake Lodge and visitors with accessible parking permits are permitted to drive up. How to get there:
-
Book a Parks Canada shuttle from Lake Louise
-
Use Roam Transit from Banff
-
Join a guided tour with a commercial operator
-
Bike the road if you are feeling adventurous
The shuttle system is extremely popular in September, so reserve early.
Hiking Tips
-
Arrive 15 to 30 minutes before your planned shuttle or trail start for the best views and lighter crowds
-
Bring layers, as mountain weather can change from warm sun to snow in minutes
-
Carry bear spray and hike in a group, as this is prime grizzly territory
-
Pack enough water and snacks, since there are no services once you leave Moraine Lake
-
The best photos come in early morning or late afternoon light, so plan your timing if you want the perfect shot

There is nothing like watching the sunrise hit a valley filled with golden larches, framed by rugged peaks and glacial lakes. Whether you stop at Larch Valley or push to Sentinel Pass, this is one of the most memorable hikes in the Rockies.
