Grassi Lakes is one of the most famous short hikes near Canmore, Alberta, known for its striking turquoise lakes, Rocky Mountain scenery, waterfall views, and relatively accessible trail. Under normal conditions, the hike is a popular choice for families, beginners, photographers, and travelers who want a memorable mountain experience without committing to a full-day trek.
However, there is an important update for anyone planning a trip in 2026: Grassi Lakes is currently closed until further notice because of a June 2026 rockslide and associated slope-stability concerns. The closure includes the Grassi Lakes Day Use Area, Interpretive Trail, Upper Trail, and surrounding access.
That means this guide is useful both for understanding the trail and for planning a future visit—but you should always check the latest official status before travelling.

What Are Grassi Lakes?
Grassi Lakes are two small, vivid turquoise lakes located in the mountains above Canmore. Their intense blue-green appearance contrasts dramatically with the surrounding limestone cliffs, evergreen forest, and Rocky Mountain landscape.
The lakes are the destination of two established hiking routes. The easier route follows an old road through forest, while the Interpretive Trail provides a more challenging climb with waterfall and valley views.
The hike’s combination of short distance + dramatic scenery + proximity to Canmore is what makes Grassi Lakes so popular.
It is not a wilderness expedition requiring an entire day. Instead, it is the kind of trail that can fit into a morning, afternoon, or larger Canadian Rockies itinerary.
Where Is Grassi Lakes?
Grassi Lakes is located near Canmore, Alberta, in the Canadian Rockies.
The trailhead is associated with Ken Ritchie Way and the Spray Lakes Road area, west of Canmore.
For visitors staying in Canmore, the location is particularly convenient because the trail is only a short distance from town.
The area is also connected to the broader Canmore Nordic Centre and Kananaskis trail network.
Getting to Grassi Lakes From Canmore
Under normal conditions, drivers travel toward the Canmore Nordic Centre and continue toward the Grassi Lakes access area.
However, do not attempt to drive to the trailhead during the current closure. Access roads and the surrounding area have been affected by the 2026 rockslide closure.
When the area eventually reopens, follow the current directions and access instructions from Alberta Parks rather than relying on an older map or travel article.
Is Grassi Lakes Open in 2026?
No. Grassi Lakes is currently closed until further notice as of August 2026.
Alberta Parks closed the area after a June 2026 rockslide. The closure includes:
- Grassi Lakes Day Use Area
- Grassi Lakes Interpretive Trail
- Grassi Lakes Upper Trail
- Reclaimer Trails
- Portions of surrounding access
The closure was implemented because of rockslide and slope-stability concerns.
This is the most important information to know before planning a Grassi Lakes hike in 2026.
Do not enter a closed area, even if older websites or social-media posts show people hiking there.
How Long Is the Grassi Lakes Hike?
Under normal conditions, the complete Grassi Lakes outing is generally around 4 km (2.5 miles), depending on the route and whether you complete a loop or return along the same trail. Travel Alberta lists approximately 4 km and 1–2 hours.
Different trail resources report somewhat different distances and elevation figures because they may measure slightly different route combinations.
For planning purposes, a useful expectation is:
- Distance: about 4 km
- Time: approximately 1–2 hours of hiking
- Difficulty: easy on the easier route; intermediate on the Interpretive route
- Elevation: roughly 125–170 m depending on the route/source
If you hike slowly, take photographs, enjoy the lakes, or stop for breaks, allow additional time.
How Hard Is Grassi Lakes?
One of the reasons Grassi Lakes attracts so many visitors is that it offers impressive scenery without the distance of a major mountain hike.
But the difficulty depends on which route you use.
Grassi Lakes Upper Trail
The Upper Trail is the easier option. Alberta Parks describes it as following an old road through dense forest.
This is generally the better choice for:
- Beginners
- Families
- Visitors who prefer a gradual climb
- Hikers who want the simplest route
- People with limited hiking experience
The route still involves uphill walking, so “easy” should not be interpreted as completely flat.
Grassi Lakes Interpretive Trail
The Interpretive Trail is more challenging.
It climbs through forest and reaches a steeper section with views of a waterfall and Canmore. Alberta Parks identifies this route as intermediate and notes approximately 125 m of elevation gain in its trail information.
It is a better choice for hikers who want:
- More challenging terrain
- Waterfall scenery
- Views toward Canmore and the Bow Valley
- A more interesting climbing experience
The Interpretive Trail is also subject to seasonal restrictions and should only be used when officially open and safe.
What Is the Grassi Lakes Trail Like?
The trail begins in a forested mountain environment and gradually gains elevation toward the lakes.
The experience changes as you climb.
At first, the forest dominates the landscape. As you gain elevation, mountain views begin opening up. On the Interpretive route, the waterfall and viewpoints add additional interest before you reach the lakes.
Eventually, the forest opens around the turquoise water, revealing the distinctive cliffs and mountain scenery that make Grassi Lakes famous.
The destination feels much more dramatic than the relatively short approach might suggest.
Why Are Grassi Lakes So Blue?
The turquoise color is one of the main reasons people search for and photograph Grassi Lakes.
The color comes from the interaction of light with minerals and fine particles in the water. The result is an intense blue-green appearance that can look almost unreal against the surrounding rock and forest.
Water color can vary with lighting, weather, season, and viewing angle, so photographs taken on different days may look surprisingly different.
What Can You See at Grassi Lakes?
The Two Turquoise Lakes
The lakes themselves are the main attraction.
Their vivid color contrasts with the surrounding limestone cliffs and evergreen forest, producing one of the most recognizable landscapes near Canmore.
Waterfall
The Interpretive Trail provides views of a waterfall during the ascent.
Water levels and appearance naturally change throughout the year, so the waterfall may look very different in spring, summer, fall, and winter.
Canmore and Bow Valley Views
The more challenging route provides viewpoints toward Canmore and the Bow Valley.
These views are an important reason some hikers prefer the Interpretive Trail when it is open.
Limestone Cliffs
The cliffs surrounding the lakes create a dramatic backdrop and are also associated with rock climbing.
Visitors should respect climbing areas and never approach unstable rock or restricted zones.

Best Time to Visit Grassi Lakes
The best time depends on the experience you want—and whether the trail is officially open.
Summer
Summer is normally the most popular season.
You can expect:
- Longer daylight hours
- Green vegetation
- More comfortable hiking conditions
- Strong turquoise colors
- Busy trails
The major disadvantage is crowds.
Canmore itself advises visitors to start early or travel during off-peak hours to avoid congestion.
Fall
Fall can provide cooler temperatures and changing foliage.
The contrast between autumn colors, turquoise water, and mountain rock can make this an excellent photography season.
Winter
Winter changes the experience considerably.
Snow and ice can make the trail more difficult, and equipment such as microspikes may be appropriate on icy sections.
Travel Alberta notes that the easier route can remain available in winter under normal conditions, while the Interpretive Trail has winter restrictions.
Always check current trail conditions before winter hiking.
Spring
Spring can bring changing trail conditions, melting snow, mud, and slippery sections.
Rather than assuming the trail is ready because temperatures have warmed in Canmore, check the official trail report before leaving.
What Is the Best Time of Day to Hike Grassi Lakes?
When the trail is open, early morning is generally the best choice for visitors who want fewer crowds and easier parking.
Early starts also give you more flexibility if you want to spend additional time photographing the lakes or exploring other Canmore attractions afterward.
Canmore’s visitor guidance specifically recommends getting an early start or visiting during off-peak hours to beat the crowds.
Midday during a summer weekend is typically a less desirable option if your priority is solitude.
Parking at Grassi Lakes
Parking is one of the practical issues visitors should consider because Grassi Lakes is extremely popular.
The Town of Canmore advises visitors not to park on shoulders or roadways when a parking location is full. Instead, visitors should consider other transportation options or have a backup plan.
During the current 2026 closure, however, visitors should not travel to the closed trailhead simply to look for parking.
When the area reopens, check current parking rules and access information because arrangements can change.
Can You Take Public Transit to Grassi Lakes?
Normally, yes.
Roam Transit Route 12 provides seasonal service between downtown Canmore and Grassi Lakes, along with stops serving places such as Quarry Lake and the Canmore Nordic Centre. Canmore states that local Roam service is free.
However, there is an important current restriction: Roam’s latest service update says Route 12 is not currently accessing the Grassi Lakes trailhead because of environmental hazards on the road.
Therefore, do not assume that a normal summer schedule means the bus is currently reaching the trailhead.
Is Grassi Lakes Family Friendly?
Under normal conditions, yes, the easier route is a popular family hiking option.
Travel Alberta specifically describes Grassi Lakes as a short, picturesque trail that is great for families.
Families should still consider:
- Children’s hiking ability
- Weather
- Trail conditions
- Steep sections
- Ice and snow
- Wildlife
- Exposure around cliffs and rock
The Interpretive Trail is less suitable for very young children or anyone uncomfortable with steeper terrain.
And, most importantly, families should not enter the area while it remains closed.
Can You Bring Dogs to Grassi Lakes?
Dog rules can depend on the current trail and wildlife restrictions.
Canmore advises visitors to keep dogs leashed outside designated off-leash areas because dogs can disturb wildlife.
Before bringing a dog after the trail reopens, check the current Alberta Parks rules and any wildlife advisories.
Do not bring a dog into a closed area.
Is Grassi Lakes Accessible for Strollers or Wheelchairs?
Grassi Lakes should not be treated as a fully accessible wheelchair trail.
The route includes uneven natural surfaces and uphill sections, and the Interpretive Trail contains steeper terrain and stairs.
Some visitors may manage portions of the easier route with suitable equipment, but conditions vary.
If accessibility is an important requirement, verify current trail conditions and accessibility information before visiting rather than relying on generic “easy hike” descriptions.
Is There a Fee for Grassi Lakes?
Access rules and provincial-park requirements can change, so visitors should check the current Alberta Parks and Canmore information before travelling.
Canmore also notes that Alberta Parks has implemented a permit system in the area and that license plates are scanned at Grassi Lakes and the Canmore Nordic Centre.
Because the area is currently closed, do not plan a visit based on older fee or parking information.
What Should You Bring?
When the trail is open, Grassi Lakes does not require a huge amount of specialized equipment, but a sensible day-hiking setup is recommended.
Bring:
- Water
- Snacks
- Comfortable hiking footwear
- Weather-appropriate layers
- Rain or wind protection
- Sun protection
- A charged phone
- Offline maps
- Bear spray where appropriate
- Microspikes during icy conditions
- Hiking poles if useful for balance
Mountain weather can change quickly, even when conditions in Canmore look pleasant.
Wildlife and Bear Safety
Grassi Lakes is in a mountain environment where wildlife awareness is important.
Canmore recommends travelling in groups, carrying bear spray, keeping dogs leashed outside designated off-leash areas, and staying out of designated wildlife corridors and closed areas.
If the trail reopens, check the latest wildlife alerts before starting your hike.
Never approach wildlife for photographs, feed animals, or leave food and garbage behind.

Grassi Lakes Safety Tips
A safe visit begins before you reach the trail.
Check the Official Status
This is especially important in 2026.
The trail is currently closed because of rockslide and slope-instability concerns.
Do not rely on an old blog post, Google Maps review, Instagram photograph, or previous hiking experience to determine whether the trail is open.
Stay on Designated Trails
The Grassi Lakes area is within a wildlife corridor, and Alberta Parks restricts travel to designated trails.
Do not create unofficial shortcuts.
Watch for Ice
During cold seasons, natural ice can make apparently easy terrain dangerous.
Microspikes and poles can be useful when conditions warrant them.
Respect Closures
A closure is not a suggestion.
If Alberta Parks has closed the area, wait for the official reopening.
Grassi Lakes vs. Other Canmore Hikes
Grassi Lakes is particularly appealing because of its short distance and dramatic destination.
| Hike Type | Grassi Lakes Advantage |
| Short scenic hike | Excellent |
| Family outing | Good on easier route |
| Waterfall views | Yes |
| Turquoise lake scenery | Excellent |
| Big elevation challenge | No |
| Solitude | Usually poor during peak periods |
| Photography | Excellent |
| Beginner-friendly | Generally yes on easier route |
| Full-day adventure | Better options exist |
If your goal is maximum scenery for relatively little hiking, Grassi Lakes is hard to beat.
If your goal is solitude, a major summit, or a long backcountry adventure, another Canmore-area trail may be a better fit.
What to Do Instead While Grassi Lakes Is Closed
Because Grassi Lakes is currently closed, travelers should have a backup plan.
Nearby Canmore offers many other walking and hiking opportunities. The Town of Canmore lists trails including the Policeman’s Creek Loop, Engine Bridge Loop, East Bow River Trail, North Bow River Trail, Quarry Lake Loop, and West Bow River Pathway.
One particularly easy alternative is Policeman’s Creek Loop, which is 1.24 km and generally takes 15–30 minutes. The Engine Bridge Loop is another scenic option, covering about 2.03 km.
Always verify that your chosen alternative is open and suitable for current conditions.
Grassi Lakes Photography Tips
Grassi Lakes is an excellent destination for landscape photography when open.
For the best results:
- Visit early to reduce crowds.
- Photograph the lakes from designated viewpoints.
- Include surrounding cliffs for scale.
- Try wider compositions that show the forest and mountains.
- Photograph in changing light rather than relying only on bright midday conditions.
- Avoid stepping into restricted or environmentally sensitive areas for a better angle.
The turquoise water is already the visual centerpiece, so simple compositions often work best.
Is Grassi Lakes Worth Visiting?
Absolutely—when it is open and safe.
Grassi Lakes offers an unusually high scenic payoff for a short hike. You get turquoise lakes, mountain scenery, forest, cliffs, and waterfall views without needing to spend an entire day on the trail.
It is particularly worthwhile for:
- First-time visitors to Canmore
- Families
- Beginner hikers
- Photographers
- Travelers with limited time
- Visitors looking for a short Rocky Mountain hike
Its popularity is also its biggest drawback. During busy periods, the experience can feel crowded.
