Two small lakes on a heather ridge in the Diamond Head corner of Garibaldi Park — the corridor’s classic hut hike, walked in summer and skied in winter, and better in both than the photos suggest.
Every mountain town has one trail that everyone has done, and above Squamish that trail is Elfin. It leaves the Diamond Head parking lot on an old road grade — wide, steady, almost polite — and climbs through big timber to Red Heather Meadows, where a small day shelter marks the point the forest gives up. From there the grade rolls along an open ridge for the better part of an hour: heather on both sides, Atwell Peak’s black pyramid filling the skyline ahead, and, on a clear evening, the whole Tantalus Range catching the light across the valley. Then the trail drops a bend and the two lakes appear below you, exactly where the name promised they’d be.
On paper it sounds like a slog — roughly eleven kilometres each way, on the order of six hundred metres of climbing. In practice the road grade does something unusual: it makes twenty-two kilometres feel moderate. There’s no scrambling, no rooty staircase, no exposure. Just distance. Fit hikers jog it, families string it out over a full day, and because the grade was built as a road, mountain bikes are allowed as far as Elfin — a two-hour climb and a twenty-minute descent that locals treat as a workout with a view (bike rules can shift, so check the current BC Parks page before rolling up).
What the distance buys you is the setting. The lakes sit in a saddle of rolling heather with volcanic rock underfoot and glaciated volcano overhead — a combination that exists almost nowhere else within an hour of a highway. In late summer the meadows go purple. In October the bears come through to work them. In winter the whole ridge disappears under metres of snow and turns into something else entirely, which is why this guide has two halves.
A word on the name, because first-timers ask: there are two lakes, they are small, and neither is the point on its own. The point is the ridge they sit on — the long heather shoulder with Atwell and Mount Garibaldi stacked behind it, and sunset falling on the Tantalus across the valley. People carry camp chairs eleven kilometres for that hour of light. Having watched it, we can’t call them wrong.
From downtown Squamish, follow Mamquam Road east as it leaves the neighbourhoods and starts to climb. The pavement gives way to roughly sixteen kilometres of gravel, gaining steadily through second-growth toward the Diamond Head trailhead. Most of it is ordinary logging-road driving — washboard, potholes, the occasional confident Corolla — but the grade steepens meaningfully near the top, and that’s where low-clearance cars and summer tires earn their regrets. The road climbs out of the Mamquam valley, which is a destination in its own right and has its own guide.
Two practical notes. First, the lot: it fills early on every fair-weather weekend, summer and winter both, and there is no meaningful overflow. Second, the season: this road climbs high enough that conditions at the trailhead routinely lag town by a month. Check current road and park conditions with BC Parks before committing — especially October through June.
The Elfin Lakes shelter is the reason this trail carries an overnight culture that most day hikes never develop. It’s a proper hut — bunks for around thirty-three people, a communal main floor, and walls that have absorbed forty-odd years of drying gear and card games. It books through BC Parks, reservation-only, year-round, and it books out: summer weekends and winter Saturdays are typically claimed the moment they open. If you want bunks, plan like it’s a ferry reservation, not a whim. Current fees and booking windows are on the BC Parks site.
Tent platforms sit near the hut for those who’d rather sleep outside (also reservable), and the Red Heather day shelter partway up serves as the storm refuge and lunch stop — it’s a warming hut, not an overnight option. If hut-based overnights are your thing, the sibling of this trip on the other side of town is Watersprite Lake — smaller hut, sharper cirque, same book-early reality.
The lakes sit a few steps apart and are governed by the oldest rule at Elfin: one is the camp’s drinking-water source, the other is the one you’re welcome to swim in. Signs at the lakes tell you which is which — read them, believe them.
Stay out of it. No swimming, no rinsing dishes, no dipping dogs (there are none anyway — see above). Everyone’s tea depends on it.
Snowmelt-fed and honestly cold, even in August. Glorious for about forty-five seconds, which is precisely enough.
Snow-free hiking typically arrives in July and holds into October, with the meadows at full purple in August. The trail is a conversation-pace walk the whole way — the classic first overnight for new backpackers, the classic trail-run for locals, and a legitimate bike ride if the current rules allow it.
Under snow, Elfin becomes the standard introductory overnight ski tour and splitboard trip in the Sea to Sky — a heated-hut objective with honest distance and a marked winter route that differs from the summer trail. It is beginner-friendly as ski touring goes. It is not beginner-friendly as walking goes: this is winter backcountry, full stop.
| Window | Conditions | Verdict |
|---|---|---|
| Dec – Feb | Deep snowpack, marked winter route, hut nights at their coziest. Avalanche gear and training mandatory beyond Red Heather; short days. | Ski tourers |
| Mar – Apr | The prime touring window — longer days, settled snow more often. Still full winter protocol. Book bunks far ahead. | Best winter |
| May – Jun | The awkward season: rotten snow up high, hidden hazards, a road that may or may not cooperate. Check conditions; consider waiting. | Patience |
| Jul – Aug | Snow-free trail, meadows peaking purple, swimming lake at its least punishing. Also: the crowds and the full parking lot. | Classic |
| Sep | Our pick. Stable weather, thinner crowds, first colour in the meadows, alpenglow earlier in the evening. | Best summer |
| Oct – Nov | Bears working the meadows, first snows dusting Atwell, freeze-thaw on the road. Beautiful and moody; go equipped for both seasons at once. | Shoulder |
Twenty-two kilometres is twenty-two kilometres. The moderate grade seduces people into underestimating the day; the trail out feels twice as long as the trail in, every time, for everyone. Bring more food than a “moderate hike” suggests, and headlamps whether or not you plan to need them.
The ridge between Red Heather and the lakes is gorgeous and exposed — to sun in August, to weather the rest of the year. When cloud sits on Diamond Head, the famous views are simply gone, and more than one party has walked eleven kilometres to photograph the inside of a marble. Check the forecast with your hopes switched off.
And the hut is a shared bunkhouse, not a cabin rental. It’s sociable, warm, occasionally loud, and entirely dependent on everyone packing out their own mess. The place runs on the honour system, and it shows — in both directions. This is Sḵwx̱wú7mesh Úxwumixw territory; walk it like a guest, because you are one.
No boats at 1,480 metres — Elfin earns its views on foot. But if you’re staging a hut trip out of Squamish, a couple of local services take the friction out of the logistics.
Overnight kit you’d rather not fly with — camping and outdoor gear from local owners, dropped where you’re staying. Handy when the hut booking came through before the packing list did.

Find a localAbout 11 km each way — 22 km round trip — from the Diamond Head trailhead, with on the order of 600 m of elevation gain. Because the route follows an old road grade through Red Heather Meadows, it’s long rather than steep: most day hikers take 6–8 hours return, trail runners much less, and overnighters split it with a night at the hut or tent platforms.
In summer, it’s one of the most beginner-friendly alpine trips in the corridor — moderate grade, no technical terrain, a day shelter partway. The catch is pure distance: 22 km is a real day, and the return leg is where unprepared parties suffer. In winter it is a different question entirely; see below.
Yes. The shelter — bunks for roughly 33 people — is reservation-only through BC Parks, year-round, as are the tent platforms beside it. Popular dates book out well in advance, especially summer weekends and winter Saturdays. Current fees, booking windows, and rules are on the BC Parks website; the Red Heather shelter en route is a day-use warming hut only.
One of the two lakes is the designated drinking-water source and is off-limits for swimming and washing; the other is the swimming lake. Signs posted at the lakes tell you which is which — check them on arrival rather than trusting the internet, and respect the split. Fair warning: the swimming lake is snowmelt-fed and cold all season.
Historically yes — bikes have been allowed on the road grade as far as Elfin Lakes, and the descent is a local favourite. Park rules can change, though, so check the current BC Parks page for Garibaldi before you commit to riding. Beyond the lakes, bikes don’t belong on the hiking trails.
Yes — it’s the classic introductory overnight ski tour and splitboard trip in the Sea to Sky, and snowshoers do it too. But the terrain beyond Red Heather carries avalanche exposure, and the marked winter route differs from the summer trail. Carry transceiver, probe, and shovel; get avalanche training (AST 1 at minimum); travel with partners; and check the avalanche forecast. “Beginner tour” means beginner for ski touring, not a walk.
Garibaldi Provincial Park’s day-use pass requirement applies seasonally — check BC Parks for the current dates and how to book before you drive up. Dogs are not permitted anywhere in Garibaldi Park, in any season, including at Red Heather and the hut. This one is enforced and worth respecting; the meadows are active wildlife habitat, with bears working them in fall.
From Squamish, Mamquam Road turns to gravel and climbs about 16 km to the trailhead, steepening near the top. Most vehicles manage it in dry summer conditions, but clearance helps, and in shoulder season and winter the upper road holds snow and ice — winter tires are essential and the final pitch is the crux. The lot fills early on fair-weather weekends year-round. Check current road conditions with BC Parks before you go.
More from this shelf of the range: Watersprite Lake, the other hut hike east of town; the Mamquam valley the access road climbs out of; and Alice Lake for the easy day after.
