Trillium Boulder is a bouldering area in Massachusetts, about 2.5 miles from the town of West Townsend. It sits among a cluster of other bouldering spots, with State Line Boulders and Gem Boulder each about 0.1 mile away, and Townsend Conjecture Overhang at the same distance. The area is a compact, close-together collection of boulders rather than a single climb. The climbing here is all bouldering, with 13 routes spread across the V0 to V7 range. The easiest is Lemon Squeezy at V0, and the hardest is Fire at V7. The median grade is V3, so the area works for climbers of all levels. Some of the routes have named first ascents, including Lemon Squeezy by Ryan Loiselle and Fire by Crimpdaddy. Summer is the most comfortable time to visit. Typical averages from a nearby weather station in Fitchburg run to highs around 81°F in July, with lows near 61°F. Winters are cold, with January highs around 34°F. Old Rusk Quarry is about 1.4 miles away for more bouldering. For time off the rocks, the Brook Trail is about 2.4 miles away, and the Trilogy - Northeast Singletrack mountain bike route is about 2.8 miles away.
