Hard Knocks Boulder is a bouldering area in College Rock Park in Massachusetts, on city land. It sits right next to College Rock and Main Crag, both climbing areas within about a tenth of a mile, so it makes an easy addition to a visit to the park's rock. The area has 10 bouldering routes, all rated on the V scale from V0 to V7. The easiest are The Militant Fist and The Physicist, both V0, and the hardest is Problem Set at V7. Knockin' Traverse is a V3-4 traverse. The routes were first climbed by Gus Lambregst and Larry LaForge around 1981. For timing, late spring and early fall are the most comfortable. Typical averages from a nearby weather station in West Medway show May highs around 71°F and September highs around 76°F, while winter brings regular snow days from December through February. The Orange Trail and College Rock Run are both about 0.4 miles away. Paddlers can reach the Sudbury River about 5 miles off, and West Hill Park offers camping roughly 8 miles away.
