The Grassi Lakes Trail is a popular and relatively short day walk located near Canmore, Alberta, Canada. It offers a rewarding experience with stunning scenery, including vibrant turquoise lakes, dramatic rock formations, and panoramic mountain views. The trail is known for its accessibility and the striking beauty of its destination, making it a favourite for locals and tourists alike. Due to its popularity, especially during peak season, arriving early is highly recommended to secure parking.
The Grassi Lakes Trail is a gem in the Canmore area, providing a relatively short but invigorating hike to two picturesque alpine lakes. The trail is divided into two main routes: the "Easy" route and the "More Difficult" route. The easy route is a wider, more gradual path, suitable for families and those seeking a less strenuous ascent. The more difficult route, however, is steeper, rockier, and features more challenging terrain, including some sections with chains to assist climbers and hikers. Both routes converge near the top, leading to the breathtaking Grassi Lakes.
The lower lake is a brilliant, almost unreal shade of turquoise, a colour attributed to the fine glacial silt suspended in its waters. The upper lake is equally beautiful, often appearing a deeper blue or green depending on the light and conditions. Surrounding the lakes are towering limestone cliffs, popular with rock climbers, and the majestic peaks of the Canadian Rockies provide a dramatic backdrop. The trail winds through a mixed forest of lodgepole pine and spruce, offering shade and a pleasant walking experience. Wildlife sightings are possible, including deer, chipmunks, and various bird species. The area is also known for its geological features, showcasing the powerful forces that shaped the Rocky Mountains.
This trail is a perfect example of how a short hike can deliver immense scenic rewards. It’s an ideal option for a half-day excursion, allowing ample time to enjoy the lakes, take photographs, and appreciate the natural beauty of the Bow Valley. The accessibility from Canmore makes it a convenient choice for visitors staying in the town or nearby Banff.
The Grassi Lakes area has a rich history tied to early European settlement and resource extraction in the Bow Valley. The lakes are named after Lawrence Grassi, an Italian immigrant who arrived in Canada in 1909. Grassi was a prospector and trapper who spent many years exploring the mountains around Canmore. He was known for his solitary nature and his deep connection to the wilderness. He is credited with discovering the lakes and is remembered for his contributions to the early exploration of the region.
In the early 20th century, the area was also significant for its coal mining industry. Canmore was a bustling mining town, and the surrounding mountains provided resources that fuelled its growth. While the Grassi Lakes themselves were not directly mined, the trails and access routes were often established by individuals like Grassi who were familiar with the terrain for prospecting or trapping purposes. The development of the trail system has evolved over time, with Parks Canada and local authorities working to maintain and improve access while managing the increasing popularity of the area.
The land on which the Grassi Lakes Trail is situated is part of Treaty 7 territory, the traditional territory of the Blackfoot Confederacy, Kainai, Piikani, Siksika, and Sarcee, as well as the Stoney Nakoda First Nations, including the Bearspaw, Chiniki, and Wesley bands. Indigenous peoples have lived in and travelled through this region for thousands of years, developing a deep understanding and connection to the land, its resources, and its spiritual significance. While the modern trail is a product of European settlement, it traverses land that holds profound cultural and historical importance for the First Nations of this territory. Understanding this context adds another layer of appreciation to the natural beauty and the human history of the Grassi Lakes area.
The Grassi Lakes Trail is typically accessible from late spring through autumn, with the prime hiking season running from May to October. During these months, the weather is generally favourable for hiking, though it can be highly variable in the Rocky Mountains.
Spring (May - early June): As the snow melts, the trail becomes accessible. Wildflowers begin to bloom, adding splashes of colour to the landscape. However, early spring can still see lingering snow patches, especially on the more difficult route, and the lakes may still be partially frozen or have ice along their edges. The weather can be unpredictable, with a mix of sunny days and cooler, rainy periods.
Summer (mid-June - August): This is the peak season for Grassi Lakes. The lakes are at their most vibrant turquoise, and the surrounding vegetation is lush and green. The weather is typically warmer, with long daylight hours. However, this is also the busiest time, and the parking lot can fill up very early, especially on weekends and holidays. Afternoon thunderstorms are common in the Rockies during summer, so it's advisable to start your hike in the morning and be prepared for sudden changes in weather.
Autumn (September - October): Autumn offers a spectacular display of golden larch trees and crisp, clear air. The crowds begin to thin out, making it a more peaceful time to visit. The lakes remain beautiful, and the mountain scenery is often at its most dramatic with clear skies. However, temperatures can drop significantly, and early snowfalls are possible, especially in late October. It's essential to check weather forecasts and trail conditions before heading out.
Winter (November - April): The Grassi Lakes Trail is generally not recommended for hiking during winter due to snow, ice, and avalanche risk, particularly on the more difficult route. While experienced winter hikers with appropriate gear (crampons, ice axe) might attempt it, it is considered an advanced winter route. The lakes will be frozen over, and the landscape will be covered in snow.
Early Morning (e.g., 8:00 AM - 9:00 AM): Arrival and Parking
Morning (e.g., 9:00 AM - 10:30 AM): Ascent to the Lakes
Midday (e.g., 10:30 AM - 12:30 PM): Exploring Grassi Lakes
Afternoon (e.g., 12:30 PM - 2:00 PM): Descent and Departure
Important Notes:
Grassi Lakes is a very popular day hike, so planning is key to a successful and enjoyable visit. The primary logistical challenge is securing parking, as the trailhead parking lot is relatively small and fills up extremely quickly, particularly on weekends, holidays, and during the summer months. Arriving as early as possible, ideally before 9:00 AM, is strongly advised. If the main lot is full, alternative parking may be available at the Canmore Nordic Centre, which is a short walk or cycle ride from the Grassi Lakes trailhead. This adds a small amount of distance to your day but is a viable option.
Canmore is the closest town and serves as an excellent base for exploring Grassi Lakes and the surrounding Bow Valley. Canmore offers a wide range of accommodation options, from budget-friendly hostels and campgrounds to mid-range hotels and luxury resorts. It also boasts a vibrant downtown area with numerous restaurants, cafes, gear shops, and grocery stores, making it convenient for stocking up on supplies or enjoying a meal after your hike. Public transport options to the trailhead are limited, so a private vehicle is generally the most practical way to access Grassi Lakes.
This is a day hike requiring no overnight accommodation.
No permits are required for day use of the Grassi Lakes Trail. Access to the trailhead and the trail itself is free of charge. However, it is important to note that while no specific permit is needed for hiking, visitors are expected to adhere to all park regulations and guidelines, including those related to waste disposal, staying on marked trails, and respecting wildlife.
Parking at the Grassi Lakes trailhead is on a first-come, first-served basis. During peak season, especially on weekends and holidays, the parking lot can fill up very early in the morning. It is highly recommended to arrive before 9:00 AM to increase your chances of securing a parking spot. If the main lot is full, alternative parking may be available at the Canmore Nordic Centre, which is a short walk or cycle from the trailhead.
While no permits are required for this specific day hike, it's always a good practice to check for any local advisories or temporary closures that might be in effect. Information can usually be found through the Town of Canmore or local tourism websites.

The Grassi Lakes area and its surroundings offer a wealth of activities for visitors looking to extend their stay or explore beyond the immediate trail:
Trail Conditions: The Grassi Lakes Trail is generally well-maintained. However, the "More Difficult" route can be steep, rocky, and slippery, especially after rain or in early spring/late autumn when ice may be present. Always check current trail conditions before you go, especially if planning to hike in the shoulder seasons.
Weather: Mountain weather is notoriously unpredictable. Be prepared for rapid changes, including sudden rain, wind, or even snow, regardless of the season. Check the forecast before you leave and pack layers of clothing. Afternoon thunderstorms are common in the summer months; it is advisable to start your hike early in the morning to avoid being caught out in a storm.
Wildlife: While generally safe, you are in bear country. Carry bear spray and know how to use it. Make noise while hiking to avoid surprising wildlife. Never feed animals, as this can lead to dangerous habituation.
Rock Climbing Hazards: The cliffs around Grassi Lakes are popular with rock climbers. Be aware of your surroundings, especially if you are hiking the more difficult route, as falling rocks or equipment are potential hazards. Always maintain a safe distance from climbing areas.
Crowds: Due to its popularity, Grassi Lakes can be very crowded, especially during peak season. This can sometimes detract from the wilderness experience. Arriving early is the best way to mitigate this. Be patient and courteous with other hikers.
Emergency Preparedness: Inform someone of your hiking plans, including your expected return time. Carry a fully charged mobile phone, although reception can be spotty in the mountains. Consider carrying a personal locator beacon (PLB) for remote areas or if hiking alone.
The Two Lakes: The primary points of interest are the Grassi Lakes themselves. The lower lake is known for its striking turquoise colour, a result of fine glacial silt suspended in the water. The upper lake is often a deeper blue or green and offers a slightly different perspective. Both lakes are ideal for photography and quiet contemplation.
Rock Climbing Cliffs: The sheer limestone cliffs surrounding the lakes are a major attraction for rock climbers. While not a side trip for most hikers, observing climbers in action can be fascinating. The routes here are well-established and attract climbers from around the world.
The "More Difficult" Route Features: For those who choose the steeper, more challenging path, the trail itself offers points of interest. Sections with chains bolted into the rock provide assistance on steeper ascents and descents, adding an element of adventure. The views from this route are often more expansive as you gain elevation more quickly.
Forest Environment: The trail passes through a beautiful mixed forest of lodgepole pine and spruce. Take time to appreciate the diverse plant life, listen to the birdsong, and enjoy the dappled sunlight filtering through the trees.
Canmore Nordic Centre: While not directly on the Grassi Lakes trail, the adjacent Canmore Nordic Centre is a significant point of interest. It offers extensive mountain biking trails, disc golf, and in winter, world-class cross-country ski trails. It's a hub of outdoor activity.
