A spectacular, waterfall-filled cirque near Cascade Pass and Sahale Arm, Horseshoe Basin is just far enough away from both trailheads that access it to warrant making it an overnight trip. But you'll need to be sure to have your backpacking permits should you elect to hike here.
Please note that the mileage indicated here is for the Horseshoe Basin trail itself. It's 17 miles and 4550 feet of elevation gain to the basin from Cascade Pass.
Horseshoe Basin is accessible via either the Upper Stehekin Valley Road, or Cascade Pass. Choose your approach, and near Pelton Basin Camp, turn east onto a narrow, sometimes brushy trail.
It's a steep climb; more than 1300 miles in just over a mile and a half, but you'll be rewarded with scenery right out of a fairytale. Waterfalls cascade from glaciers that are just out of sight above the valley walls, lush greenery abounds, and views of the valley across the way, complete with staggering mountain views are stunning.
