Peninsula Overhang is a bouldering area in Massachusetts, about 1.2 miles from the town of Dedham Island. It sits among several other climbing spots, including Overshadowed, Warm-Up Boulder and Wilson Mountain Reservation, all within about a tenth of a mile. The area is a cluster of boulders rather than a single route. Six bouldering problems make up the crux, with grades ranging from V0 to V7. The easiest is Centerpiece at V0, and the hardest is The Stage at V7, which was first climbed by Jonathan Gregg. Late spring and early fall are the most comfortable times to go. Typical averages from a nearby weather station in Jamaica Plain show May highs around 69°F and September highs around 75°F, while July averages about 85°F. Other climbing is close by, with Eastern, MA about 2.7 miles away. Mountain bikers can head to Powerglide, about 2.2 miles off, and paddlers can reach the East Branch Neponset River, roughly 7 miles away.
