- best months
Upper Boulders is a bouldering area in the Pyramid Mountain Natural Historic Area in New Jersey, on county land. It sits among a cluster of climbing spots, with Lower Boulders and Christopher's Rock each about 0.1 mile away, and the Pink Trail and Black Dot on Pink Trail hikes about 0.2 mile off. The area has seven bouldering routes, all rated from V0 to V3+. The easiest is Warm Up at V0, and the hardest is Triceratops at V3+. Harold's Razors is a V3 route, and Harold's Boulder is a V0+ boulder with a first ascent by Justin Moran in May 2020. For comfortable weather, late spring and early fall are the best bets. Typical averages from a nearby weather station show May highs around 70°F and September highs around 75°F, with July the warmest month at about 83°F. Other climbing is close by at Upper Solitude, about 1.9 miles away. Paddlers can reach the Rockaway River, about 7.8 miles off.
