Before you head up

Weather in the mountains turns quickly. Afternoon thunderstorms build over the Rockies on many summer days, snow can fall on high trails in any month, and a cold, clear night often leaves frost at the trailhead while the ridge above is milder.

In national parks, check Parks Canada trail reports and closures before a long day out, and in winter and spring read the Avalanche Canada forecast for the area you plan to enter.
