Cory Pass – Edith Pass Loop

This is a demanding, big‑mountain loop that rewards effort with jaw‑dropping scenery and a taste of Banff’s wilder side. Plan on roughly 8.5 miles total (13–14.5 km), 3,000+ feet of gain (~900–1,040 m), and 5–8 hours on trail. It’s steep, rocky, occasionally exposed, and less crowded than Banff’s headline hikes—perfect if you like a challenge and can handle loose footing.

Route overview

Start from the Fireside Day Use / Cory Pass Trail Parking. A mellow warm‑up through aspen and meadow quickly gives way to a relentless climb up the south side of Mount Edith. Most hikers go clockwise: ascend to Cory Pass first, then descend via Edith Pass—safer and easier than downclimbing the steepest, loosest bits. From Cory Pass (around 2,350 m), soak in wide panoramas of Mount Louis, Mount Cory, Mount Edith, and the Bow Valley. Drop into otherworldly Gargoyle Valley—named for its eroded limestone pinnacles—and traverse long scree slopes beneath Mount Edith before a gentle rise to Edith Pass. The return loses itself into pine forest and a rough, rooty trail back to the lot; look for Parks Canada markers near treeline on the Edith side to stay on track.

Difficulty and hazards

Expect steep switchbacks, airy traverses across gullies, short hands‑on moves, and plenty of loose scree—especially entering/leaving Gargoyle Valley. The footing keeps you honest even on the descent, and route finding can get murky on the Edith side. Trekking poles (and even gaiters) help a lot. There are no reliable water sources past the initial creek; carry what you need. Snow/ice can linger into late June and return by late September; winter travel is not recommended due to avalanche risk.

Scenery, geology, and wildlife

This loop strings together classic Rockies limestone—sheer walls, knife‑edge ridges, and the striking spire of Mount Louis. Gargoyle Valley’s eroded pillars feel otherworldly, and summer meadows near the start pop with wildflowers. Keep an eye out for hoary marmots basking on boulders; bears are seen less frequently, but it’s still bear country.

Best time to hike

Late June through early September is your sweet spot for dry, snow‑free travel and long daylight. Start early for cooler temps on the initial climb and better light at the pass. Shoulder seasons can be icy high up; save it for a firm melt‑out window. It’s never “busy” by Banff standards, but earlier starts and weekdays add solitude.

Tips

• Go clockwise (Cory Pass first) to tackle the steepest, loosest terrain on the way up.
• Poles, sturdy boots, layers, and a map/GPS are smart; the scree can obscure the tread.
• Bring plenty of water; refills are unreliable after the first mile.
• Carry bear spray and know how to use it.

Trailhead & parking

Park at the Fireside Day Use / Cory Pass Trail Parking off the Bow Valley Parkway (Highway 1A), just west of the town of Banff. From the lot, cross the bridge and pass a picnic area with a stone fireplace to reach the loop junction.
