A chunk of Banff National Park—one of Canada’s most iconic outdoor destinations—is still off-limits to visitors two weeks after a rock slide crashed down near a popular hiking trail by the falls. Parks Canada isn’t taking any chances, keeping the area closed while they assess the risks.

Editor’s Note: For hikers and nature lovers, this is a bummer—especially in peak summer season. But it’s also a reminder of how unpredictable mountain terrain can be. Parks Canada’s caution makes sense (no one wants a repeat slide with people around), but it’s a headache for travelers who had their hearts set on hitting those trails. The closure also hints at the bigger challenge of balancing access with safety in parks facing more extreme weather and erosion.
