Larch Valley at a glance
Larch Valley is a high meadow above Moraine Lake with the Minnestimma Lakes at its upper end. The trail starts behind the lodge at the lake and climbs 570 m over 4.5 km. The park rates it moderate and gives 3.5 to 4 hours for the whole round trip. Sentinel Pass continues from the valley to the pass at 5.6 km one way and is rated difficult.
The valley is known for its larches. These are conifers that turn gold and drop their needles in autumn, which is why the late September weeks are so popular. You reach the trailhead by shuttle, not by private car, so read the Moraine Lake shuttle guide first. If you prefer a ready-made day, see Moraine Lake tours from Banff, Calgary and Lake Louise.

Trail figures. The climb is the ascent on the way out.
| Trail | One way | Round trip | Climb | Total time | Rating |
|---|---|---|---|---|---|
| Larch Valley and Minnestimma Lakes | 4.5 km | 9.0 km | 570 m | 3.5 to 4 hours | Moderate |
| Sentinel Pass via Larch Valley | 5.6 km | 11.2 km | 750 m | 4.5 to 5.5 hours | Difficult |
| Eiffel Lake (branches off the same route) | 5.7 km | 11.4 km | 560 m | 4 to 5 hours | Moderate |
| Wenkchemna Pass | 9.6 km | 19.2 km | 1,015 m | 7 to 8 hours | Difficult |
For most visitors in larch season, Larch Valley is the right goal. It gives the gold meadow and the lakes without the steep final section to the pass. Add Sentinel Pass only if you are fit, start early and have the return bus in mind. Both routes share the first stretch, so you can decide at the valley.

When the larches turn gold
Late September is the usual answer, but the colour is not on a schedule.
Late September
Larches in the Larch Valley turn golden especially at the end of September. The peak changes from year to year with the weather, so there is no fixed date.
Weekends are busiest
September weekends are the busiest time at the lake. Go on a weekday if you can. Organise transport early and choose an early bus.
Cold and snow in autumn
At the Lake Louise weather station, September averages a daily high of 14.7 °C and a low just below freezing (1981 to 2010 normals). Moraine Lake sits higher, and the valley is higher still. Bring warm layers, gloves and a hat, and be ready for snow higher up.
Plan the bus first
The regular shuttle runs every 30 minutes from 06:30 to 17:00 from the Park and Ride, with the last return at 19:30. In 2026 the season ended on 12 October. Early starters can take the Alpine Start bus at 04:00 or 05:00 from Lake Louise Lakeshore, booked by 15:00 the day before. Read when to visit Moraine Lake for the wider season.
Sentinel Pass
Sentinel Pass is the harder extension. It follows the Larch Valley route to the pass, is 5.6 km one way with 750 m of climbing and is rated difficult, with 4.5 to 5.5 hours for the whole route. Take the Larch Valley route and not the much longer Paradise Valley route, which is a different hike.
Turn back if the weather changes, if there is snow on the slope or if your group is tired. The park advises against the moderate and difficult routes from mid-October to mid-June because of avalanche exposure. Do not go into avalanche terrain.
Trail rules, bears and groups
The advice is the same in the larch weeks as at other times.
Travel in a tight group
The current trail advice is to hike in a close group of at least four people, stay alert, make noise and carry bear spray you know how to use. This is a recommendation, not a fixed seasonal rule. A group requirement can be ordered when bear activity calls for it, and notices at the trailhead will say so.
What group access means
Where it is ordered, at least four people stay close together, and the first and last person can talk to each other at a normal voice. Check the latest trail notices before you set off. For more on staying safe, see the Banff wildlife guide.
Keep distance
Stay at least 100 m from bears, wolves, cougars and coyotes, and at least 30 m from deer, elk, sheep and moose. Do not feed or approach animals, and keep dogs on a leash.
Carry the basics
Bring water, warm layers and emergency gear. Do not rely on mobile signal, Wi-Fi or running water. Stay on marked trails and do not collect rocks or plants.
