Cuba Boulder is a bouldering area in Massachusetts, set within the Webster Conservation Area. It sits among a cluster of climbing spots, with Temple Area, Pusherman Wall and Hermit's Cave all about 0.1 mile away, and Starbag Boulder at a similar distance. The area is a compact, close-knit bouldering hub rather than a single route. The climbing here is all bouldering, with five routes spread across the V1 to V6 range. The easiest is 90 Miles at V1, and the hardest is Castro's Cross at V6. The median grade is V2, so the area suits climbers of all levels. For comfortable weather, late spring and early fall are the sweet spots. Typical averages from a nearby weather station in Jamaica Plain run to highs around 69°F in May and 75°F in September, while July highs average about 85°F. Beyond the boulders, the Charles River Greenway and Walking City Trail Section 3 are both about 3.2 miles away, and the Sudbury Aqueduct Trail, a mountain biking route, is about 3.4 miles off.
