Picture this. You begin the hike on the wide and well-maintained West Rim Trail. It follows the river and then crosses the bottom of the canyon, surrounded by 270-million-year-old layers of rock. Relaxing, right? Just wait for it. The trail then starts to climb via a series of switchbacks leading up the side of the mountain. Then more switchbacks: 21 tighter turns, called “Walter’s Wiggles,” where elevation levels rapidly increase. Your heartbeat is probably rapidly increasing at this point, too.
On top of Walter’s Wiggles, you can stop for a stunning view (perhaps with a marriage proposal) and a restroom stop while you contemplate the final stretch of the hike. If you’re afraid of heights, it’s best to turn back now. The last stretch is the real test of bravery.
