Nira Rock

Nira Rock is a bouldering and climbing area in Boston, Massachusetts, on city land within the Nira Avenue Rock land unit. It sits about a mile from the Jamaica Plain neighborhood, and the closest trail is Walking City Trail Section 3, less than a mile away. The area has 16 routes, with 11 of them bouldering problems and four top-rope climbs. The bouldering runs from V0 to V6, with the Nira Project at V6 being the hardest, and the top-rope routes include Ivy Tower, which is also a boulder problem. The climbing is best suited to a day of bouldering, with the boulders clustered close together. For comfortable weather, late spring and early fall are the sweet spots.
