Phantom Boulder is a climbing area on Lynn Water Supply Land in Massachusetts, about 0.1 mile from Sponsor Boulder, Behemoth Boulder, Evil Boulder and Grenade Boulder. The cluster of boulders sits on the same stretch of land, so it's easy to pair with other boulders in the immediate area. Late spring and early fall are the most comfortable times to visit. Typical averages from a nearby weather station in Reading show May highs around 70°F and September highs around 75°F, with July the warmest month at about 84°F. Shark's Tooth East and Deep Woods Trail West, both mountain biking routes, are about a mile away. Eagle Rock Trail, a hike, is about 1.5 miles off.
