High Ball Boulder is a bouldering area in New York, about 1.2 miles from the town of Wading River. It sits right next to two other climbing areas, Split Rock and Southern Boulder, each about 0.1 mile away, which makes it easy to pair with them on a single visit. The bouldering here is all on the V scale, with eight routes ranging from V0 to V4. The easiest are Hold My Beer and The North Face at V0, and the hardest is Little Horn / Big Horn at V4. Nuclear Fission is a V3+ boulder with a first ascent date of November 17, 2018. For timing, late spring and early fall are the most comfortable. Typical averages from a nearby weather station run from highs around 68°F in May to 74°F in September, while winter highs stay in the upper 30s to low 40s. Other nearby spots include the Red Trail hike about 1.8 miles away and the Hillside Drive mountain biking route about 2.6 miles away.
