Parks Canada has officially reopened the popular Bow Glacier Falls Trail in Banff National Park. It's been closed for more than a year following a tragic cliffside collapse that shook the hiking community.
If you are planning to head out to Bow Lake to hike this classic trail, things look a bit different now. There is a serious conversation we need to have about personal responsibility in the backcountry.

The mountains are beautiful, but they aren't theme parks. They don't have safety nets.
What Happened at Bow Glacier Falls
On June 19, 2025, the peacefulness of the Bow Valley was shattered in less than sixty seconds. Analysts at Condé Nast Traveler have provided expertise on this trend.
Without warning, a massive section of the cliffside—estimated at 1,000 cubic meters of rock—collapsed to the right of the waterfalls. The falling debris rapidly shattered, showering blocky rocks and a choking dust cloud over the lower basin.
Several hiking groups were in the immediate vicinity. While emergency crews scrambled to reach the remote location, taking nearly an hour to arrive, the aftermath was devastating. Ten people suffered injuries, and three required hospitalization.
Tragically, two hikers lost their lives: Jutta Hinrichs, 70, a retired university educator, and Hamza Benhilal, 33.
The trail was immediately shut down. Parks Canada enforced strict closure orders, threating violators with fines of up to $25,000. The area remained off-limits until a thorough geological review could be completed.
What the Geotechnical Report Reveals
To figure out if the trail could ever be safe again, Parks Canada commissioned a detailed geotechnical assessment by BGC Engineering. The findings, compiled by geological engineer Dave Gauthier, tell a fascinating yet sobering story of a landscape in transition.
The basin around Bow Glacier Falls was covered by glacial ice up until about a century ago. Because of this recent de-glaciation, the entire valley is in what geologists call a "paraglacial" period. Basically, the slopes are still actively adjusting to the loss of ice that once held them up. This means we should expect high rates of erosion, landslides, and rockfalls as the mountain tries to find its balance.
Here are the key takeaways from the scientific assessment:
- More slides are coming: It is entirely reasonable to expect future rockfalls from both the original June 2025 collapse site and other parts of the rock face.
- Unstable material remains: While the bulk of the loose rock fell during the initial disaster, hung-up debris is still sitting on the cliffs and could come down at any time.
- The official trail is mostly safe: The report notes that a "significant reduction in life safety risk" can be achieved simply by keeping hikers out of the active debris runout zones. The established trail itself is mostly located outside the high-risk impact zones.
How Parks Canada is Managing the Risk
Instead of keeping the trail closed forever, Parks Canada decided to reopen it by relying on public education and clear boundaries.
They've installed highly visible signs marking the exact end of the official 2.8-kilometer trail. These signs warn hikers in no uncertain terms that stepping beyond that point puts them in a high-hazard rockfall zone.
But let's be realistic: there are no physical barriers. There is no ranger standing there to stop you from walking right up to the base of the waterfall.
François Massé, superintendent of the Lake Louise, Yoho, and Kootenay field unit, put it bluntly:
"Anywhere in the mountains there are risks present. This is not a controlled environment. This is not a mall."

Your Safety Guide for Hiking Bow Glacier Falls
If you decide to hike this gorgeous trail, you must change how you approach backcountry safety. Don't just mindlessly follow the dirt path. Use these practical steps to protect yourself and your group:
1. Respect the Signage
This isn't a suggestion. When you reach the sign marking the end of the official trail, stop. Do not hike up the steep slopes or scramble closer to the waterfall basin where the runout from rockfalls is concentrated. You can still enjoy spectacular views of the falls from a safe distance.
2. Move Efficiently and Avoid Lingering
If you are hiking the final stretch of the basin, don't stop to have a picnic, change your socks, or take a long break. Keep moving through any narrow sections or areas flanked by steep moraine slopes.
3. Listen to the Mountain
Rockfalls often give a warning, even if it's brief. Witness reports from the 2025 slide mentioned hearing several smaller, trickling rockfalls in the minutes leading up to the massive collapse. If you hear cracking, popping, or what sounds like distant thunder, look up immediately, identify your escape route, and move away from the cliffs.
4. Carry Communication Gear
Cell service is virtually non-existent along most of the Icefields Parkway. The rescue in 2025 was initiated because a hiker was carrying a satellite GPS transponder. Never head into the Banff backcountry without a satellite communication device (like a Garmin inReach) to call for help in an emergency.
Next Steps for Your Hike
Before you pack your bags and head out to Bow Lake, make sure you take these active steps:
- Check the Trail Reports: Visit the Parks Canada trail conditions website for Banff National Park to ensure there are no temporary closures or active hazard warnings.
- Pack the Essentials: Ensure your group has a satellite messenger, bear spray, extra warm layers, and sturdy hiking boots.
- Establish a Group Plan: Talk with your hiking partners before you start. Agree beforehand that everyone will respect the safety signs and that nobody will cross into the hazardous zone at the end of the trail, regardless of how tempting the view looks.
