Hidden Wall is a bouldering area in Camden Hills State Park in Maine, managed by State Park and Recreation. It sits among a cluster of other bouldering spots, with Burried Treasure boulder, Guide's Wall and Crack House boulder all about 0.1 mile away. The climbing here is all bouldering, with nine routes ranging from V2 to V6+. Summer is the most comfortable time to visit. Typical averages from a nearby weather station run to highs around 77°F in July, with September still near 69°F. That station sits a few hundred feet lower than the park, so temperatures on the boulders run a little cooler. The closest trails are Slope Trail and Adam's Lookout Trail, each about half a mile away. For paddling, the Ducktrap River is roughly 7 miles off.
