The Grand Canyon is a popular tourist destination in the United States, and one of the best ways to explore the area is by taking a MULE or BURRO ride. Mules are four-legged pack animals that have been used for centuries to carry goods and people over long distances. They are known for their strength and sure-footedness, making them ideal for traversing the steep terrain of the Grand Canyon. Burros are similar to mules, but they are smaller and more agile. They are also used as pack animals, and are often seen carrying supplies up and down the canyon's trails.
