Cascade Canyon South
What to Expect
Safety Advisory
This is prime grizzly bear country, especially in late summer when bears forage in the berry patches along the trail. Carry bear spray accessible on your hip, not buried in your pack, and make noise through the brushy sections.
Afternoon thunderstorms roll in fast above treeline from July through September. If you're pushing toward the Alaska Basin, start early and plan to be below the exposed ridgeline by early afternoon — lightning up here has nowhere to go but through you.
Snow lingers in the upper south fork well into July most years. Check conditions with the Jenny Lake Ranger Station before heading out, as creek crossings can be treacherous during peak snowmelt.
Trail Details
Pro Tips
Take the Jenny Lake boat shuttle across to shave off the flat, unremarkable two-mile lakeside approach — your knees will thank you on the way back, and you'll save energy for the actual canyon.
Cache extra water at the Cascade Canyon fork junction on your way in. The south fork has fewer reliable water sources than the north fork, and on hot August days you'll drink more than you planned.
The meadows about two miles past the fork explode with lupine, paintbrush, and columbine in mid-July — bring a macro lens if you're a wildflower photographer, because the alpine light here in early morning is absurdly good.
