In shortBlock out 2.5 to 3 hours for the round trip: Parks Canada measures the walk up to the teahouse at 3.9 km each way with 495 m of gain and grades it moderate. It starts at the Lake Louise shoreline, climbs in switchbacks through forest past Mirror Lake and finishes at a teahouse at 2,135 m. The teahouse takes cash only, and the route is avalanche terrain from November through mid-May.

How long the Lake Agnes tea house hike takes
Parks Canada puts the Lake Agnes trail at 3.9 km one way with 495 m of elevation gain, rates it moderate and allows 2.5 to 3 hours round trip. That covers walking and a short pause; it leaves no room for a sit-down lunch, so add whatever time you plan to spend at the top.
Banff & Lake Louise Tourism publishes shorter figures for the same path: 3.4 km one way with 385 m of gain, also 2.5 to 3 hours return, and elsewhere 7 km return with 405 m of gain in about 2 hours. Plan on the Parks Canada numbers and treat anything quicker as a bonus. The trail report at the Lake Louise Visitor Centre beside Samson Mall is where you confirm conditions on the day.
The climb is steady and never technical. It starts gaining height at the first bend and keeps gaining it in short switchbacks, which is why people who stroll the flat lakeshore path without noticing the altitude find this one hard work. Lake Louise sits at 1,731 m and the teahouse at 2,135 m.
Mirror Lake and the climb above Lake Louise
You start at the lakeshore in front of the Fairmont Chateau Lake Louise, on the same paved path everyone uses for photographs. A few hundred metres along the northern shore the signed trail turns uphill to the right and the crowd thins within minutes, because most people carry on along the flat.
From there it is forest and switchbacks. The grade eases at Mirror Lake, a small pond under the cliffs of the Big Beehive, and that is where most hikers decide whether they want the rest of it. Above the pond the switchbacks tighten again and the final pitch climbs beside the stream draining out of Lake Agnes.
The top is a cirque: Lake Agnes filling a bowl of rock, the Big Beehive rising on the far side, the teahouse set on the lip above the outflow. Turn around on the way back down and the view opens over Lake Louise, 2.4 km of it, with Mount Victoria and its hanging Victoria Glacier closing the end of the valley.
Teahouse hours and the cash-only rule
Carry cash. The Lake Agnes Tea House takes no cards and no digital payments, and there is nothing at 2,135 m to fall back on if you arrive with a phone and a plan.
Parks Canada gives the teahouse season as mid-May to just after Canadian Thanksgiving in mid-October, for this teahouse and the one at the Plain of Six Glaciers. Banff & Lake Louise Tourism lists a narrower window, mid-June to early October, with daily hours of 8 a.m. to 5 p.m. The two do not match, so at the edges of the season walk up expecting the view and check ahead if the pot of tea is the point of the day.
From November to May the building is shut. The trail is still there, and the switchbacks above Mirror Lake are avalanche terrain through those months, which is covered below.
Set off early, and what goes in the pack
Be walking by 8 a.m. from June through October. One path carries everyone, the teahouse has a finite number of seats, and the bottleneck starts before you reach the water: Parks Canada says the Lake Louise Lakeshore lots fill extremely early and stay full all day in peak season, and it names the Parks Canada shuttle or Roam Public Transit as the way to see the lakes rather than a private car.
Shuttle seats carry a mandatory reservation and there are no walk-up places. In 2026 the Lakeshore service ran May 15 to October 12, with departures from the Park and Ride every 30 minutes from 6:30 am and the last return at 7:30 pm, which gives comfortable cover for a 2.5 to 3 hour climb if you take an early bus. Roam Route 8X also reaches the lakeshore from downtown Banff, every day of the year, and Roam puts that ride at about 1 hour 20 minutes, time you have to subtract when you work back from an 8 a.m. start on the trail.
There is no water on the way up. The climb never lets off, and the teahouse is cash only, so fill a bottle before you leave the valley. Footwear needs grip more than stiffness: the surface is packed dirt, roots and rock, often wet in the trees, and old snow sits in the upper switchbacks well into the summer.
- Enough water for the full round trip, filled before you reach the trailhead
- Cash, in small notes, if you plan to order anything at the teahouse
- Shoes or boots with tread; the upper switchbacks hold snow and mud
- Layers: July averages 21 C by day and 5 C overnight at the lake, and it is colder at 2,135 m
- A park pass, which is required and is separate from any transport booking
- Distance from wildlife: 30 m from deer, elk, sheep and moose, 100 m from bears, wolves, cougars and coyotes, and feeding or disturbing animals is illegal
The months when this climb is off the table
From November through mid-May these switchbacks are avalanche terrain, and Parks Canada states that the teahouse hikes are not safe in that stretch of the year; it also cautions that a signposted winter route is not automatically a safe one. Pick a different walk if you are visiting in the cold half of the year.
The edges of the season need care as well. Parks Canada rates the Plain of Six Glaciers area for spring avalanche conditions in May and June, the alpine hiking season proper begins in late June, and the teahouse trails are listed June to October as the practical snow-free window. Snow can fall up there at any time, July included.
October closes the window from the other end. The last week of September into the first week of October is when larch colour around Lake Louise reaches its peak, by which point days average 8 C and nights -5 C and the teahouse is within days of closing for the year after Canadian Thanksgiving. The lake itself stays open year round, and in winter the Fairmont runs the natural rink on the ice, lit after dark.
A full day at both lakes from Banff
An 8 to 10 hour day trip from CAD 79 that covers the transfer, the Moraine Lake permit and access fee and a driver and guide, which leaves the hours you get at Lake Louise as the one thing to plan around.

Where the trail goes next
Two more routes leave from the teahouse. Parks Canada lists the Big Beehive as a 1.5 km side trip with 150 m of gain and 115 m of loss, which buys you the view straight down onto Lake Louise from the cliff edge above Mirror Lake. Taken as a hike in its own right, Banff & Lake Louise Tourism rates the full Big Beehive difficult at 5.4 km one way with 731 m of gain and 4.5 to 5 hours return.
The glacier valley is the other direction. Head that way instead of up to Lake Agnes and you get 5.9 km one way, 595 m of gain with 250 m of loss, moderate, roughly 4 hours on your feet, the Victoria Glacier and Mounts Victoria and Lefroy ahead of you, and at the far end a teahouse the Canadian Pacific Railway put up in the mid-1920s. That one is cash only too. Linking both teahouses from the Chateau in one loop comes to about 14.5 km, a full day that needs an early start and settled weather.

Does the climb fit your day
If you can manage 495 m of continuous gain and you are at the shoreline by 8 a.m., the answer is yes, with hours left over afterwards. Arrive at midday in August, or come to it without much steady uphill behind you, and Mirror Lake is a sensible turnaround; the gradient above the pond is the part that decides most people.
On a scheduled day trip the operator sets the length of the Lake Louise stop, so the hike only works if the itinerary gives you the hours. The Lake Louise Moraine Lake Day Trip from Banff Calgary Canmore is an 8 to 10 hour day from CAD 79, with the Moraine Lake permit and access fee included with the ticket inside the June 1 to October 11 or 12 window and lunch taken at Lake Louise Village. Its pickups leave Calgary Downtown at 07:50, Canmore at 09:20 from the Travel Alberta Canmore Visitor Information Centre and Banff at 09:45 from the Elk + Avenue Hotel at 333 Banff Ave. Check the stop length with the operator before booking if the teahouse is the reason you are coming.
Questions people ask
Is the hike suitable for children or first-time hikers?
Parks Canada rates the Lake Agnes trail moderate, and the work is 495 m of gain packed into 3.9 km, with no scrambling or exposure. Fit children who are used to walking uphill manage it with breaks, and anyone unsure can treat Mirror Lake as the turnaround, since the steepest switchbacks come after it. Allow more than the 2.5 to 3 hours if you stop often.
Do I need to book anything to reach the trailhead?
The trail starts at the Lake Louise lakeshore, so the booking question is about getting there. Seats on the Parks Canada shuttle are reservation-only, with nothing sold at the door, and in peak season the lots beside the lake are full from very early in the morning right through to the end of the day. Roam Route 8X serves the lakeshore from downtown Banff daily all year, with reservations advised May to October. A park pass is required separately from any transport.
Can I do Lake Agnes and the Plain of Six Glaciers on the same day?
Yes, and the loop linking both teahouses from the Chateau comes to about 14.5 km. Walked on its own, the Plain of Six Glaciers side adds up to 5.9 km one way, 595 m up and 250 m down, about 4 hours there and back. Combining them means leaving the shore early, carrying food and water for the whole day, and accepting that both teahouses take cash only.
Are there bears on this trail?
Banff National Park holds an estimated 65 grizzly bears, and grizzlies leave their dens from late March to mid-May while shrub berries ripen from about mid-July to early August. On the trail that means holding back 100 m if you see a bear, wolf, cougar or coyote, and 30 m for deer, elk, sheep and moose. Where Parks Canada imposes Group Access, hikers must travel in a tight group of four or more, so check the current restrictions on the trail report before you set out.
Which week should I come for the larches?
Peak larch colour around Lake Louise falls in the last week of September and the first week of October, with the trees beginning to turn through the second half of September. That overlaps with the end of the teahouse season, which Parks Canada gives as closing just after Canadian Thanksgiving in mid-October. Expect cold mornings: October averages 8 C by day and -5 C overnight at the lake, and colder again at 2,135 m.
