The Lake Agnes Tea House trail is one of the most frequently hiked routes in the Canadian Rockies. Starting from the Lake Louise shoreline in Banff National Park, it climbs steadily through subalpine forest, passes Mirror Lake, and arrives at Lake Agnes — a glacier-fed cirque lake sitting at roughly 2,135 metres above sea level. The tea house at its shore has operated since 1905 and remains accessible only on foot.
Route Overview
The trailhead begins at the Lake Louise Lakeshore parking area. From the eastern end of the lake, the path follows a well-maintained gravel track southwest before switchbacking into the forest above. The ascent is consistent but never steep enough to require hands-on scrambling. Total distance to Lake Agnes and back is approximately 14 kilometres, with around 600 metres of elevation gain on the way up.
At Mirror Lake — roughly 5 km from the start — the trail splits. The left fork continues to Lake Agnes directly; the right fork adds the Big Beehive viewpoint before descending to Agnes. The Big Beehive extension adds about 2 km and an additional 150 m of elevation, but delivers unobstructed views across the Bow Valley toward the Victoria Glacier.
Permit note: Entry to Banff National Park requires a valid Parks Canada Discovery Pass. No separate trail permit is needed for this route. The tea house operates from mid-June through early October, weather permitting.
Seasonal Conditions
The trail typically opens in late May or early June, depending on snowpack. Snow can persist on shaded sections near Mirror Lake well into June. Parks Canada updates trail conditions on their website at pc.gc.ca. In late summer and autumn, the larch forests on the upper slopes turn gold — the period from late September to mid-October is heavily trafficked as a result.
Winter travel on this trail requires avalanche awareness. The open slopes above Mirror Lake fall within terrain affected by avalanche paths during and after significant snowfall events.
Wildlife
The Lake Louise area has active populations of black bear and grizzly bear. Parks Canada requires bear spray to be carried and accessible throughout the hike. The trail sees enough foot traffic that solo encounters are less common than on quieter routes, but the standard precautions apply: make noise while moving, travel in groups where possible, and do not approach or feed any wildlife. Hoary marmots are common along the rocky sections near Lake Agnes.
Gear Checklist
- Bear spray — required and must be accessible, not stowed in a pack
- Waterproof hiking boots with ankle support
- Layering system — temperatures at lake level drop considerably even in summer
- Trekking poles (useful on the descent, especially on wet surfaces)
- Minimum 2 litres of water — the tea house sells beverages but potable water sources on trail are limited
- Sun protection — the exposed ridge sections receive direct UV at altitude
- Basic first aid kit
- Navigation backup — a downloaded offline map or printed Parks Canada trail map
Getting to the Trailhead
The Lake Louise area is located approximately 57 km northwest of Banff townsite on the Trans-Canada Highway (Highway 1). Take Exit 177 toward Lake Louise Village, then follow Lake Louise Drive to the Fairmont Chateau Lake Louise parking area. The parking lot charges daily fees during peak season and frequently fills before 9 am on weekends from July through September. Parks Canada operates a shuttle service from Lake Louise Village during high season — details at Parks Canada shuttle page.
Emergency Contacts
Banff Dispatch (Parks Canada): 403-762-1470. In emergencies, call 911. Cell signal is available near the trailhead but unreliable above the treeline. Carry a fully charged device and consider an emergency beacon on multi-day extensions into the backcountry.
