Natural Arch
About
Natural Arch is a natural arch in Yuma County, Arizona, sitting at about 3,015 feet inside the Kofa Wilderness. The surrounding land is part of the Kofa National Wildlife Refuge, managed by the U.S. Fish and Wildlife Service, and the nearest town is La Paz Valley, about 15.5 miles away. Winter and early spring are the most comfortable times to visit. Typical averages from the nearby Kofa Mine weather station show January highs around 67°F and lows near 49°F, while summer highs climb into the 100s. That station sits well below the arch, so temperatures at the arch run cooler. Two trails lie within easy reach. Signal Peak Trail is about 3.4 miles away, and Palm Canyon Trail is about 5.4 miles away.
