Quicksilver Cove

A swimming hole with a headframe at the bottom

You smell the cold before you see the water. The trail drops through pine, the rock opens up, and there it is: a sheer-walled bowl of water the colour of polished silver shading to deep blue, ringed by cliffs the old crews blasted out of the mountain. It is so clear that the first time, you misjudge the depth completely. What looks like an arm's reach below the surface is twelve metres of nothing.

Quicksilver Cove is a drowned mine. The water you swim in fills the Pelletier Stope, once the richest silver shaft on the Silvercrest. Look straight down on a still morning and the past is right there under you: the timbers of the sunken headframe, and an ore cart still parked on its rails where the miners left it the night the lake came up through the floor.

The night the mine drowned

In 1911 the Pelletier Stope was running deep and rich. Then, on a single cold night that autumn, the crews “hit the lake's roots” — an underground spring that opened without warning and filled the workings before dawn. Everyone got out. The mine did not. By morning the shaft was a pool, and the headframe stood in water to its shoulders.

The water settled clear and strange. Mineral walls leached a faint silver-blue into it, the same trick of light that gives Silver Lake its name a thousand feet below. Locals will tell you it is the same water, really, that the mine just found a shortcut to the lake's reflection. On a flat morning the cove goes mirror-still and you can't tell the cliff from its double.

Swimming and cliff-jumping

The cove has three main ways in. A gentle ledge on the shallow side lets you wade and warm up. A floating dock sits anchored over the deepest part for sunbathing and a breather. And the cliff-jump ledges — marked and graded by height — step up the east wall for those who want the drop.

• The low ledge, about two metres, where everyone starts.
• The mid ledge, around five metres, the workhorse jump.
• The high ledge, the tallest marked jump; check the posted sign and the water below every single time.

Why the water is that colour

The silver-blue isn't a filter or an algae bloom. The old stope walls are threaded with pale carbonate and sulphide minerals that scatter blue light and reflect it back up through exceptionally pure, sediment-free spring water. Because nothing washes silt in — no creek feeds the cove, only the spring rising from below — the clarity holds, and you get sightlines down to the headframe that you simply do not get in a normal lake.

How to visit

Drive up Silvercrest Way and turn onto Mine Road; the day-use lot is signed at the trailhead. From the lot it's a short, steady five-minute walk down to the water. The cove is a free, walk-in City site. Lifeguards are on duty through the summer season; posted hours and the swim-safe flag are at the trailhead board.

Spring and fall are stunning but unguarded and very cold; treat them as look, don't leap. Winter freezes the rim into something otherworldly — worth the walk for the view alone, but the cove is closed to swimming. For broader water-safety guidance, see the City's preparedness page.
