Paramount Rock is a climbing area in Idaho on Bureau of Land Management land within the Upper Snake Field Office. It sits among several other climbing and outdoor destinations, with Kelly Island Campground less than a mile away and Heise Rock and the Northeast Wall about a mile off. The climbing here is a mix of sport and mixed routes, with the sport style dominating. Fifteen routes are listed, and the grade range runs from 5.8 to 5.11b, with a median of 5.9. Among the named routes are Fly By Night at 5.8, Positively Negative at 5.11b, and Excitations, a mixed route at 5.9. The area also holds a boulder problem graded V4. The most comfortable months for a visit are typically June through September, when typical highs at a nearby weather station average from 75 to 85 degrees. That station sits about 13.6 miles away and is roughly 500 feet lower, so temperatures at the rock run cooler. Other nearby spots include the South Fork of the Snake River's Byington Boat Access, about 1.2 miles away, and the Kelly Mountain hike, about 2.2 miles away.
