Castle Dome

Utah

About

Castle Dome is a summit of 7,060 feet in the Zion Wilderness, part of Zion National Park in Utah, managed by the National Park Service. The nearest town is Springdale, about 6 miles away. For comfortable weather, aim for late spring or early fall. Typical averages from a nearby weather station show May highs around 69°F and September highs around 77°F, with lows in the 40s. That station sits a few hundred feet lower than the summit, so temperatures up top run a little cooler. The Grotto & Base of Great White Throne climbing area is about half a mile away, and the Lower Emerald Pool Trail is under a mile off. Angel's Landing is about 1.3 miles away, and Watchman Campground, roughly 4.7 miles away, is the closest place to camp.
