This four-day rim-to-rim traversal might pose a challenge even to avid adventurers. You need to be able to hike four to seven miles per day while carrying a full daypack. Due to its length (24 miles), change in elevation (up to 4,000 feet in a single day) and temperatures prone to dramatic swings, this trip is suited for intermediate and advanced hikers. To ensure that everything goes as smoothly as possible, you should consider yourself healthy and active before taking on this challenge. If the trek is too difficult, there are plenty of less strenuous Grand Canyon hikes to get started on.
