The Larch Valley and Sentinel Pass hike from Moraine Lake is one of the best days you can have in Banff National Park. Golden larch trees, a panoramic view of the Ten Peaks, and the incredible blue water of Moraine Lake — it earns its reputation. I’ve done this trail four times now, including twice during larch season, and it still delivers.

Shuttle/Transit: Roam Transit has offered a direct route to Moraine Lake, though some years they don’t, you can check their website to be sure. Otherwise, take Roam Transit to Lake Louise and connect to the Parks Canada Moraine Lake shuttle, which requires booking online the day reservations open.

Getting There
Moraine Lake has been closed to private vehicles for several years now, and that’s unlikely to change. The most affordable option is Roam Transit, which sometimes runs a direct route to Moraine Lake. Unfortunately this service isn’t guaranteed every year, so check their website before planning your trip.
If Roam Transit isn’t running to Moraine Lake directly, take it to Lake Louise Village and connect to the Parks Canada shuttle. That shuttle requires advance booking and sells out fast. Check the Parks Canada website for current pricing and availability, definitely don’t show up hoping to figure it out on the day.
Private shuttles are available if you miss the booking window, but they cost more. However, they’re probably the most convenient choice. Either way, sort your transportation before you do anything else. Getting to the trailhead is the hardest logistics problem this hike presents.
The Hike
The trail to Larch Valley starts at the Moraine Lakeshore and climbs immediately. It’s a steady switchback through pine forest where you can catch glimpses of the glowing teal blue Moraine Lake through the trees.
The switchbacks go on for quite some time but most reasonably fit people can complete it without issue. The trail is safe, well-maintained, and easy to follow. After roughly 2.5 km you break out of the trees and into Larch Valley proper, and the landscape shifts completely.
What does Larch Valley actually look like in fall?
In larch season, the valley is pure gold. The larches turn a warm yellow that sits against the gorgeous mountains and blue sky in a way that feels almost unreal. On my October 2025 trip there was a dusting of fresh snow on the peaks above, which made the color contrast even sharper.
The valley itself is has minimal elevation gain and is an enjoyable walk. Near the end, there are a few small lakes tucked into the landscape before you start the push toward Sentinel Pass which are nice break spots before the final climb begins.
If you’re planning a fall trip to the area, it’s worth knowing that the Larch season in the Canadian Rockies window is narrow, it’s usually two to three weeks in late September and early October depending on the year.
Continuing to Sentinel Pass
Is the climb to Sentinel Pass difficult?
The final push to Sentinel Pass is a zigzag switchback up a steep open slope. It’s the hardest section of the day but it’s worthwhile for the best view of the hike. It’s not technical and very easy to see.
At the top, the view opens up across the Valley of the Ten Peaks. You can see the full sweep of those peaks with the larches below. It’s the kind of panorama that makes the elevation gain feel absolutely worth it. I’ve stood up there four times and it’s still one of the best viewpoints I know in the Rockies.
The descent follows the same route back through Larch Valley. It goes faster than the climb, and the view on the way down is just as stunning.
If you’re seeking larches without the Moraine Lake crowds, Mount Fairview and Saddleback Pass near Lake Louise offer a similarly golden payoff with a fraction of the foot traffic. The trail is steeper, but it’s a solid alternative for the same time of year if you don’t mind working a bit harder for fewer people on the trail.
Tips
Book your Moraine Lake shuttle the moment reservations open. It sells out weeks in advance during larch season, sometimes faster.
Go early in the day if you can. The trail gets busy, especially in September and October, and Moraine Lake itself is crowded by mid-morning.
Larch season typically peaks in the last week of September but varies year to year.
Layers are essential. Even on a mild fall day, the top of Sentinel Pass is exposed and can be cold and windy. On my October trip it was a chilly day from the start.
The trail is well-marked throughout and doesn’t require navigation skills or skills in general, but trekking poles help on the descent from Sentinel Pass.
Frequently Asked Questions
How long does the Larch Valley and Sentinel Pass hike take?
Plan for 4 to 5 hours for the full hike to Sentinel Pass and back. I’ve done it in just under four hours at a fast pace. It was raining the entire time so I kept moving to stay warm.
When is the best time to hike Larch Valley for the larches?
Larch season in the Canadian Rockies typically runs from mid-September to mid-October, with peak color usually landing in the last week of September. It varies year to year, but this is the general window. I like to check AllTrails for the latest trail photos to determine when the larches are changing color.
How do you get to Moraine Lake without a car?
Private vehicles are not permitted at Moraine Lake. Your options are Roam Transit (check their current schedule as service varies by year), the Parks Canada Moraine Lake shuttle booked in advance through the Parks Canada reservation system, or a private shuttle operator. Sort this out well before your trip date, Moraine lake is a very popular location.
Is the Larch Valley and Sentinel Pass hike hard?
It’s moderate. The switchbacks up to Larch Valley are steady but manageable, and the final climb to Sentinel Pass is steeper but short. Total elevation gain is around 725 m
Can you hike Larch Valley and Sentinel Pass outside of larch season?
Yes. The trail is hikeable from July through October. The July experience is completely different. The views are of green forest beneath the stunning mountain backdrop, with way less people around compared to larch season. I hiked it in the rain in July and still had a solid day. Larch season is the headline draw, but summer hikers will have a quieter trail and just as epic mountain views.
