In spite of its name, this isn't the best place to warm up, but those looking for great V3-4 bouldering will feel right at home. This is a continuous and somewhat high wall with gorgeous, sweeping, deeply-incut rails giving rise to roughly a dozen quality problems all in a row. Lots of high cruxes and slippery, slopey mantel topouts keep it exciting.
Getting There
From the Trailer Park, walk left down the canyon for a couple minutes past many high walls (some with gnarly highball problems) until you see the Warm Up Wall on the right. The Arkansas Wall is directly across the canyon, hidden by trees.
