Egg Wall is a climbing area in Castle Rocks State Park in Idaho, managed by State Park and Recreation. It sits among a cluster of other climbing spots, with Hostess Gully - West Corridor, Castle Rock - East Face and Castle Rock - South Face all about 0.1 mile away. The area has 11 routes, with trad climbing making up most of them. The grades run from 5.6 to 5.10a/b, and the hardest route is Hard Poached. Sport climbers will find Bacon Slab and Hard Boiled, both about 5.9. Duane Ackerman is the first ascender on several of these routes. Summer is the warmest stretch for climbing. Typical averages from a nearby weather station in Oakley show July and August highs around 86°F with lows in the mid-50s, while winter highs stay near 40°F. That station sits about 1,500 feet lower than the park, so temperatures at Egg Wall run cooler.
