Bow Glacier

Overview

Bow Glacier hangs above Bow Lake on the edge of the Wapta Icefield, feeding the lake and the headwaters of the Bow River. It’s a rare day-hike chance to stare straight at an active glacier while a powerful cascade—Bow Glacier Falls—pours off the headwall below.

What You'll See

• A classic glacier–lake–waterfall combo: turquoise Bow Lake, a canyon walk, the multi-stage Bow Glacier Falls, and the ice draped above it.
• Glacially scoured rock, outwash flats, and that telltale “rock flour” color in the water.
• Big mountain backdrops (Portal Peak and neighbors) and, in places, a natural rock bridge and the junction toward the Wapta Icefield.

How to Visit

Park at the Bow Lake area by the Lodge at Bow Lake on the Icefields Parkway and follow the signed shoreline/canyon trail toward Bow Glacier Falls for the best glacier views. The glacier itself is backcountry terrain—no roads, no facilities—so treat this as a hike, not a drive-up viewpoint. A valid national park pass is required.

Seasonality

Summer brings open trails and that vivid blue water. In winter, Bow Lake often freezes and the landscape turns into a snowshoe/ski-touring expanse with broad views toward the glacier. Expect cold winds off the ice in any season.

Wildlife

This is prime bear country. Hikers are advised to carry bear spray, make noise, and keep food secured. Marmots, pikas, and alpine birds are possible along the rocky sections.

Geology & Change

Bow Glacier is an outlet of the Wapta Icefield. Its grinding ice creates fine "rock flour" that keeps Bow Lake turquoise. The glacier has retreated dramatically since the 1800s, a change you can read in the moraines, deltas, and polished bedrock around the lake and falls.

Best Time to Visit

• Summer mornings for calmer water, softer light on the ice, and better odds at parking.
• Weekdays beat weekends for crowds.
• Winter is beautiful for snowshoe views, but travel and ice conditions vary—plan accordingly.
