Welcome to Marble Canyon, a truly breathtaking slice of Arizona that marks the beginning of the Grand Canyon. You can feel the immense scale of the landscape right from your car, but the real magic happens when you step out onto the historic Navajo Bridge. It's an easy, flat walk just a few minutes from the parking area, where you'll stand suspended 467 feet above the turquoise Colorado River, often with a chance to spot soaring California condors. For a bit more adventure, take a hike along the moderate Cathedral Wash trail to get down to the river's edge and experience the canyon from a different perspective.
