Climbing Mount Logan: Canada’s Highest Peak

Mount Logan stands in the heart of Kluane National Park and Reserve, in the St. Elias Mountains of the southwest Yukon, about 40 km from the Alaska border. It rises out of the largest non-polar icefield on Earth, and there is no road anywhere near it — reaching the base means an hour-plus ski-plane flight, or one to two weeks of overland travel. Expeditions register in Haines Junction before flying in.

At 5,959 m (19,551 ft), Logan is the highest point in Canada and the second-highest in North America after Denali. It is also one of the most massive mountains on Earth by bulk, with an enormous base circumference and a broad summit plateau carrying eleven named peaks over 5,000 m. First climbed in 1925 after an epic approach, it remains rarely visited: only a few dozen climbers attempt it in a typical year, and many turn back.

The mountain sits within a UNESCO World Heritage Site shared with Alaska’s Wrangell–St. Elias and Glacier Bay parks and BC’s Tatshenshini–Alsek — one of the largest protected wilderness areas on the planet, co-managed with the Champagne and Aishihik First Nations and the Kluane First Nation. Logan’s high plateau is also one of the coldest places on Earth outside Antarctica, and its summit ice holds climate records that scientists drill as ice cores.

Logan is as much an expedition-management problem as a climbing one. The King Trench rarely demands hard technical climbing, yet it defeats strong climbers for reasons that have nothing to do with steepness:

Parks Canada regulates the Icefield Ranges tightly. You must have all of this in place before you climb:

Guiding companies operating in Kluane must be licensed by Parks Canada, so if you go guided, confirm your operator holds a current business licence for the park. Apply early: teams have been turned away for showing up without an approved permit.

Because no road comes near the mountain, nearly every expedition flies in on a ski-equipped bush plane from the Kluane Lake area to a glacier base camp around 2,750 m. The flight is short but entirely weather-dependent: teams often wait days for a window both to fly in and, crucially, to fly out. Build that uncertainty into your schedule and your food and fuel supply.

Typical camp progression (King Trench)

Camp elevations vary by team, conditions, and year — treat these as a typical shape, not a fixed plan.

Logan makes its own weather. Positioned near the Gulf of Alaska, it draws violent storms that can pin teams down for days. The widget below is a general modeled forecast for the mountain area — useful for a sense of the cold, but real expeditions rely on specialized high-altitude mountain forecasting.

The climbing season runs mid-April to late June, opening around April 10; Parks Canada permits no icefield travel between November 15 and April 9. May into June is the heart of the season, offering the longest daylight and the most workable snow, though it is still bitterly cold high on the mountain. Whatever the dates, Logan’s proximity to the Gulf of Alaska means major storms can arrive without much warning, so weather buffer days aren’t optional — they’re part of the plan.

Logan accounts for the majority of mountaineering incidents in Kluane, which is precisely why the two-person minimum and insurance rules exist. Parks Canada’s own figures give the picture: of roughly 4,000 climbers and skiers in the Icefield Ranges between 1973 and 2015, about 15 died in falls and avalanches, with many more evacuated for severe altitude sickness, frostbite, or crevasse falls. Expect to carry loads of 20–40 kg at altitudes from 2,000 to nearly 5,700 m, in conditions swinging from intense snow-glare at up to +30°C to storms with winds over 160 km/h and zero visibility.

A guided Mount Logan expedition typically runs well into five figures — roughly US $9,000–$15,000+ — reflecting the ski-plane charter, the two-to-three-week length, and guiding on a serious peak. Independent teams spend less on guiding but still face major costs: the ski-plane flights (the single biggest line item), the mountaineering permit, mandatory rescue insurance, and weeks of food and fuel. Park permit fees themselves are modest; the flights and insurance are what add up. Confirm current pricing directly with operators and Parks Canada, as figures shift year to year.

Logan demands true expedition equipment built for extreme, sustained cold and weeks of self-supported glacier travel. This is not a peak to improvise gear on.
