Grand Central Stones

At the northern edge of the Bronx, where parkland swells and the noise of the city thins, Grand Central Stones sits along the Old Putnam Trail, part of a quiet network of paths that riders, runners, and rock-hounds alike rely on. The site isn’t flashy, but it serves a clear purpose: a central landmark where boulders and rock faces draw climbers before they vanish deeper into the Palisades Interstate Park. Walkers cut through toward Jerome Park Reservoir, mountain bikers stash gear nearby, and geology buffs pause to study the quartzite slabs that give the area its name.

To reach the spot, head up to Old Putnam Trail, Bronx, NY 10471; the trail runs parallel to Gun Hill Road and offers a single pull-off just wide enough to leave a bike or set out gear. The entrance is unmarked from the road, but the outcroppings are visible from the path itself. Expect steady foot traffic during the week and a quieter scene before dawn or after dusk—ideal for those who prefer the rock to themselves. Bring a crash pad or borrow one; the landings here are uneven.

Climbers ascend the main face for top-rope sessions, while new arrivals test slabby friction climbs on the east side. Off-widths and layback lines keep more experienced hands busy, and boulderers circulate on the low-angle slabs under the pines. A smaller sector further north along the trail offers shorter walls for beginners, perfect for dialing in technique on crimps and slopers. Weekend mornings see chalk clouds drifting upward, signaling a handful of regulars already at work.
