#narrow ledge

“After a 15-minute boat ride across Waterton Lake is required to reach the trailhead, which gives it a unique, isolated feel. However, the true cut-off-from-the-world highlight of the hike, which gains 2,300 vertical feet over 5.4 miles, is a 100-foot, hands-and-knees crawl the trail takes through a natural tunnel. Along the way, you will also have to balance along a narrow ledge (the park has affixed a cable handrail if you need it) and scurry up a metal ladder via ferrata style. When you do have time to look around, take in the beauty of the park’s waterfalls, long elegant cascades tumbling down the sedimentary rock walls of the sheer peaks. The hike passes by four of them, the highlight of which is Crypt Falls, dropping close to 600 feet straight down from the hanging valley that holds the lake.”
