The steepest trail in the corridor that’s worth every step — on the order of 1,200 metres up in about seven kilometres — ending at a milk-turquoise lake, a tiny hut, and a glacier you can watch disappearing.

There is a kind of hike where the trail is the obstacle between you and the destination, and a kind where the trail is the destination. Wedgemount is stubbornly both. The destination — a milk-turquoise lake at roughly 1,900 metres, held in a stone bowl beneath Wedge Mountain, the highest peak in Garibaldi Park — is one of the great arrivals in the Coast Mountains. But nobody who has done this trail talks about the lake first. They talk about the climb.
The arithmetic is simple and merciless: on the order of 1,200 metres of gain in about seven kilometres, one-way. The trail does not believe in switchback diplomacy. It goes up, then it goes up differently, and near the top it stops pretending to be a trail at all — a rough boulder and headwall section where you use your hands, pick lines between rocks, and stop looking at your watch. Poles help enormously on the way up. On the way down they stop being optional: the descent is where knees and ankles blow up, and it takes longer than anyone plans for.
Then you top the lip of the basin and the whole ledger balances at once. The water is that improbable glacial milk-turquoise — rock flour, ground off the mountain by ice and held in suspension. Snow patches linger around the shore well into July. Marmots whistle from the boulders like referees. A small hut sits near the water, and above the far moraine the Wedgemount Glacier hangs in its shrinking corner of the cirque — more on that below, because it’s the part of this place that changes every single year.
This is not a beginner objective, and it isn’t trying to be. It’s the corridor’s honest test piece: no permit lottery drama, no famous photo prop, just a straightforward brutal climb to a place that earns every metre of it. Budget a full day. Bring more water than feels reasonable. And leave something in your legs for the way down.
Most trail profiles get drawn with a merciful vertical scale. This one doesn’t need exaggerating. Distances and elevations below are approximate — the shape is the point.
The Wedgemount Glacier has retreated dramatically within living memory. Its toe once reached down near the lake itself; today the ice sits pulled back and diminished above the moraine, and hikers who return across the decades describe the difference in the stunned tone people usually save for demolished childhood homes.
That makes this basin one of the most legible climate-change classrooms in the Coast Mountains. You don’t need a chart or a satellite pass — you stand at the lake, look at where the ice is, look at the raw scoured rock where it recently was, and do the arithmetic yourself.
Fig. 2 — Then and now, schematically. The dashed line is the part that should bother you.
Rock flour — stone ground to powder by the glacier — hangs suspended in the water and scatters the light. The colour shifts through the day and the season, and it photographs less well than it looks, which is a rare compliment.
Hoary marmots whistle from the rocks around the basin — a sharp, piercing note that sounds exactly like someone refereeing your final ascent. They’re fat, unbothered, and not to be fed. Watch from a distance and let them run the place.
The basin holds snow late — patches linger around the lake well into July, and the upper trail can carry snow when the valley is in full summer. Check current conditions before trusting a July date, and pack like the season is a month behind.
A modest mountaineering hut sits near the lake — small, simple shelter of the old school, maintained through the BCMC. Whether a night there is first-come-first-served or bookable has varied; check the BCMC directly for current rules before you build a plan around a bunk.
Treat it as a bonus, not a guarantee — and treat the building itself like the volunteer-kept artifact it is. Pack out everything.
BC Parks maintains tent platforms at the lake, and backcountry camping runs on reservations — book through BC Parks before you go up. Day-use pass requirements in Garibaldi are seasonal and change; check the BC Parks Garibaldi page for what applies to your date.
An evening and a dawn at the lake is the strongest argument for carrying overnight weight up that grade. The light show is the refund.
Wedgemount is sometimes filed under “hard hike” as if it were a Joffre with attitude. It isn’t. It’s a different category of day: this is not a beginner objective, and the people who have a bad time here are almost always the ones who treated the distance — a friendly-sounding 7 km — as the whole story. The story is the vertical.
The descent deserves its own paragraph everywhere it’s mentioned, so: the descent is the dangerous half. Tired legs, 1,200 metres of down, loose rock in the upper section — this is where knees and ankles blow up and where trips over-run their daylight. Poles, real footwear, and a turnaround time you actually honour.
The access spur off Highway 99 is short gravel; its condition varies year to year, so check recent reports before assuming any car can make it. No dogs anywhere in Garibaldi Provincial Park — that one is absolute. And the water is glacial: beautiful to look at, minutes-cold to swim in. Nobody lingers.
Nothing paddles up a headwall — there’s no rental angle at the lake and we won’t invent one. What we can do is make the logistics around the trail lighter.
Poles, dry bags, overnight kit staged to your trailhead-day plans in the corridor — so the drive north of Whistler starts with everything already sorted.
Arrange a dropFirst time up something this steep? Get a local read on conditions, timing, turnaround discipline, and whether your party and the headwall should meet this year.
Ask a localAnd for the day after — when the stairs at your rental are suddenly a moral question — the kindest thing in the corridor is flat water. An easy canoe or SUP float in Squamish through Squamish Canoe Rental uses exactly none of the muscles Wedgemount just spent, and the canoes take up to three paddlers, so the sorest member of the party can ride in the middle. Climb Saturday, float Sunday.
Genuinely hard — widely treated as the steepest worthwhile trail in the Whistler corridor. On the order of 1,200 m of elevation gain in about 7 km one-way, with almost no flat relief and a rough boulder/headwall section near the top where you’ll use your hands. Fit hikers still call it a full day. It is not a beginner objective, and it’s a poor choice for testing new boots or new knees.
Budget a full day. Climb times vary a lot with fitness, but the trap is the descent — 1,200 m of down on tired legs takes longer than the math suggests and is where injuries happen. Start early, set a turnaround time, and keep water and daylight in reserve for the way out.
Yes — a small BCMC hut sits near the lake. It’s modest, volunteer-maintained shelter, and whether a night there runs first-come-first-served or by booking has varied, so check the BCMC directly for current rules. BC Parks also maintains tent platforms at the lake with backcountry camping by reservation.
Garibaldi Provincial Park has used seasonal day-use pass requirements, and camping runs on BC Parks reservations. The rules change season to season, so check the BC Parks Garibaldi page for the dates you’re planning rather than trusting last year’s answer — or this page’s.
Yes — the glacier hangs above the basin, though far less of it than there used to be. The ice has retreated dramatically within living memory; its toe once reached near the lake. Look, photograph, and be moved — but stay off the loose moraine slopes and never walk on the glacier itself unless you’re roped, equipped, and trained for glacier travel.
No. Dogs are not permitted anywhere in Garibaldi Provincial Park — the rule covers the trail, the lake, and the campsites. Plan boarding in Whistler or Squamish if you’re travelling with one.
Late — the basin sits at roughly 1,900 m and holds snow around the lake well into July, even when Whistler valley is in full summer. Mid-July through September is the reliable window, and even then, check current conditions before you go.
