These formations frame the city and provide miles of scenic overlooks, hiking trails, and even fossil beds. From Swords Park, visitors can walk or bike along the paved trail that follows the rim’s edge, offering sweeping views of downtown, the Yellowstone River, and distant snowcapped peaks.

The Great Temple, with its four colossal statues of Ramses II seated at the entrance, was designed not only to honor the pharaoh but also to project his power to neighboring Nubia.
