The Dungeon is a climbing area within City of Rocks National Reserve in Idaho, managed by the National Park Service. There is no fee to visit. For comfortable climbing weather, late spring and early fall are the sweet spots. Typical averages from a nearby weather station run to highs around 65°F in May and 74°F in September. That station sits a few hundred feet lower than the reserve, so temperatures on the rock may run slightly cooler. Several other climbing areas sit right next door, including Electric Avenue, Ghetto Boulder and Spoon Boulder, each about 0.1 mile away. Hikers can reach Register Rock, roughly 0.3 mile off, or the Flaming Rock Trail, about 0.6 mile away.
