Big Rock is a climbing area in Washington's Iller Creek Conservation Area - Big Rock Addition, on county land. It sits among several named climbing areas, including West Face, East Face and Rocks of Sharon, all about 0.1 mile away, and The Bird Watching Boulder about 0.2 mile off. The surrounding land is managed by the county. The climbing here is sport and trad, with five routes in total. Four are sport, and one is trad. The grades run from 5.6 to 5.9, with the hardest being Around the Horn at 5.9- and Arcing Crack (aka Rescind) at 5.9. The easiest is Crown Royal at 5.6. Summer is the most comfortable time to climb. Typical averages from a nearby weather station in Spokane show July highs around 87°F with only about four wet days, while winter highs stay near freezing. That station sits roughly 1,500 feet lower than the rock, so temperatures at the crag run cooler. For a walk, Stevens Creek Trail is about 0.4 mile away and Upper Valley Trail about 0.5 mile. Iller Creek Loop is roughly 1.6 miles off.
