Walcott Quarry Burgess Shale Hike

Why go

This is the rare hike where the destination rivals the views. The Walcott Quarry sits within the Burgess Shale—one of Earth’s most important fossil deposits—so you’re not just walking to a viewpoint; you’re stepping into deep time with expert interpreters. It’s guided-only, long, and strenuous, but if fossils, geology, and big alpine scenery light you up, this is a standout day.

The hike experience

Expect a full-day push of roughly 22–23 km (13–15 miles) total with 760–850 m (2,500–2,800 ft) of gain. The route typically starts from the Takakkaw Falls parking lot, travels past Yoho Lake and along the flanks of Wapta Mountain on the Wapta Highline, then turns onto a restricted spur into the quarry area. Early on, you’ll glimpse one of Canada’s tallest waterfalls; mid-route, Yoho Lake makes a scenic rest stop; higher up, Fossil Ridge opens to sweeping views over Emerald Lake and the Yoho peaks.

The final approach is the crux: a sustained, switchbacked climb (~150 m in under a kilometer) on a mix of dirt, rock, and some loose scree. Some sections feel narrow and a touch exposed, but there are no major cliff drops. Most groups spend about an hour at the quarry itself, examining fossil-bearing shale and learning how 508-million-year-old soft-bodied sea life came to be preserved so exquisitely.

Difficulty and pace

This is a demanding day (about 11 hours). The distance, elevation, and steady group pace make it feel earned. Good fitness really matters. Trekking poles help on the steeper bits and the descent on tired legs.

Logistics and restrictions

This hike is strictly guided—access to the quarry and surrounding ridge is regulated. Advance reservations are mandatory and fill quickly (spots typically open in January). A valid national park pass is required. No dogs. Children under 8 aren’t permitted; ages 9–16 must be with an adult. Start times are early (often around 7 AM), and your guide sets the pace and schedule, including time at the fossil site.

What you’ll see and learn

Guides weave the story of the Cambrian Explosion, Charles Walcott’s 1909 discovery, and why this UNESCO-recognized site is globally significant. Keep an eye out for marmots, pikas, and mountain goats in the high country, and bring a camera for those big Emerald Lake panoramas.

Best time to hike

Guided hikes run mid-July to mid-September (e.g., July 15–September 14 in 2025) when trails are generally snow-free. Mountain weather is changeable—pack layers, rain gear, sun protection, and enough water/filtration for a very full day. Book as early as you can.

What to pack

Sturdy boots, poles, layered clothing, rain shell, sun protection, high-energy food, and plenty of water (a filter can help with refills near Yoho Lake).
