Big Brown Boulder, also known as Brown Round, is a bouldering area on Bureau of Land Management land within the Red Rock/Sloan Field Office in Nevada. It sits among a cluster of climbing and hiking spots, with Shit House Boulder and the White Rock Loop hike just 0.1 mile away. The area is a bouldering destination, with 11 routes all rated on the V scale. The easiest are V0, and the hardest reach V3. Among the named routes are G Coleman at V0, Beetle Juice at V1, and Brown Round Crack at V3. Spring and fall are the most comfortable times to visit. Typical averages from a nearby weather station show April highs around 70°F and October highs around 75°F, while July and August average in the mid-90s. That station sits about 780 feet lower than the boulders, so temperatures on the rock run cooler. Red Rock Canyon Campground is about 6.7 miles away, and the Grand Circle Trail is about 0.6 mile off.
