Millenium Boulder is a climbing area in western Massachusetts, about 1.7 miles from the town of Lake Pleasant. It sits among a cluster of bouldering and cliff bands, so it works well as a stop on a day spent exploring the surrounding crags. The most comfortable stretch for a visit is late spring through early fall. Typical averages from a nearby weather station in Leverett put May highs around 70°F and September highs around 74°F, with July peaking near 83°F. That station sits a few hundred feet lower than the boulder, so temperatures here run slightly cooler. Several other climbing areas lie close by. Left Cliff Band (Y2K9 roof) is just 0.1 mile away and Sleeping Giant Boulder is 0.2 mile away. The Hideaway is 0.4 mile off. For time on the water, the Sawmill River is about 1.7 miles away.
