Penguin Boulder is a climbing area in Black River State Forest in northern Wisconsin, managed by the State Department of Natural Resources. It sits among a cluster of other climbing spots, so it works well as one stop in a day of exploring the forest's boulders and walls. Summer is the most comfortable time to visit. Typical averages from a nearby weather station in Blair run to highs around 81°F in July with lows near 59°F, while winter highs stay in the 20s. The closest neighbors are Cube, The, Man-eater Boulder, The and Porcelain Wall, all about 0.1 mile away. Black River Falls is roughly 0.9 mile off.
