The only way to reach the Yellowstone River in the Grand Canyon area, Seven Mile Hole Trail is a doozy: You’ll drop more than 1,000 feet in just 2.3 miles going from rim to river. But first, the trail wanders along the north rim, stopping at overlooks with views of 1,200-foot Silver Cord Cascade across the canyon. Soon you’ll graduate from gazing at to hiking into the canyon, passing dormant and active hot springs along the way to the wide Yellowstone River. Keep in mind that this exposed hike can be hot, and don’t underestimate the challenge of climbing back out of the canyon.
