Regardless of how you view the Grand Canyon - braving the river rapids, hiking from rim to rim, riding a mule or stopping your car at lookouts - you won't leave without experiencing the wonderment that this awe-inspiring gorge evokes in the millions of visitors who come to see it each year. The majestic canyon, an ever-changing display of colors, stretches nearly 280 miles from end to end, is ten miles wide on the average and descends 6,000 feet at its deepest point. Take the scenic East or West Rim drive or descend into the "Inner Canyon" by foot, mule or a raft down the Colorado River, where thrilling rapids are interspersed with calmer waters. Hike down to the Havasupai Falls, where shimmering turquoise water cascades into a crystal pool below. Hiking trails abound and, for the fittest of hikers, the 21-mile rim to rim hike, while grueling in parts, is a rewarding journey. Whether watching the incredible sunset from Lipan Point, trekking down the Bright Angel Trail, the backpackers favorite, or picnicking at the popular Vista Encantadora viewing area, you'll understand why President Theodore Roosevelt declared the canyon a National Monument in 1908, calling it "the one great site which every American...should see."
