Explore Gedney Park Chappaqua Trails Beyond the Pond

Ask a Chappaqua resident what Gedney Park looks like and most will describe the same thing: the playground near the parking lot, the paved path circling the pond, maybe the sledding hill in January. Ask them what's behind that pond and the answers get vaguer. A trail, probably. Woods, somewhere back there.

New Castle's park system covers 550 acres across the town, according to the town's own Recreation and Parks page. Gedney Park alone accounts for 126 of those acres, close to a quarter of everything the town maintains. Most people who visit have walked a fraction of it.

The Park Most Chappaqua Residents Already Know

The front section of Gedney Park is the one that gets used. It has the picnic shelter by the pond, the restroom building, the wetlands area, and the sledding hill that fills up the first good snow of the season. The playground here dates to 1997, and the pond itself is younger than the park: it was built in 1971 out of what had been a marshy low point where Gedney Brook collects between two ridges, according to a local historical summary of the park.

The town bought the land in 1965 for $145,000, with New York State covering half the cost through the Land and Water Conservation Fund. A few years later, in 1969, New Castle added an adjacent two-acre parcel with a house on it, purchased from a property owner named Edward W. Terwilliger for $42,000.

A park built from two separate purchases four years apart, on land that includes a brook, two ridges, and a pond that didn't exist until 1971.

That's the version of Gedney Park most people picture. It's also roughly the front third of the property.

The Two-Thirds Behind It

Past the pond and the ballfields, the park keeps going in directions that don't show up in a quick visit. The rear area holds three irrigated baseball fields, bleachers, a second playground added in 2004, and 70 paved parking spaces, most of it built out through the early 2000s. Above that sits an upper section with a soccer field, an unpaved lot, and stretches of woodland that connect back down to the lower trails.

The trail connections between these three sections are what turn Gedney Park from a playground with a pond into an actual hike.

The Loop That Takes You Through All Three

The Gedney Park Outer Loop is the trail that stitches the property together. It runs 1.7 miles with about 278 feet of elevation gain, rated easy overall but with a steep initial climb, according to trail data on AllTrails. It takes most walkers under an hour. Unlike a lot of trails in the area that get muddy or closed in the coldest months, this one stays walkable January through November.

The route follows a straightforward blaze system if you know to look for it:

1. Start on the blue diamond blazes from the lower parking area.
2. Follow blue through the steepest early climb, which levels out after the first ridge.
3. Transition to red diamonds as the trail bends into the wooded upper section.
4. Pick up yellow diamonds on the return leg.
5. At the junction near the end where you'll see one trail marked with a single yellow diamond and another with two, take the one with two.

None of this is marked with much signage at the trailhead itself. It's the kind of detail that separates someone who's lived here a year from someone who's lived here a decade.

Where The Trail Goes If You Keep Walking

Gedney Park isn't an island. New Castle sits along a corridor that includes both the Old Croton Aqueduct Trail and the South County Trailway, two of the longer connected paths listed in regional trail directories like TrailLink. Neither trail begins or ends inside Gedney Park, but both are close enough that a resident who wants six miles instead of one and a half doesn't need to drive anywhere to get it. The aqueduct trail in particular runs largely flat and shaded, a different kind of walk than the climbs inside Gedney itself.

Treated together, the local trail network functions less like a single park amenity and more like a second, quieter road system that runs underneath the one everyone drives on.

One Closure Worth Building Around This Summer

That second road system matters more than usual right now, because the first one has a gap in it. The New York State Department of Transportation is replacing a culvert on Route 117 at Old House Lane in New Castle. According to the town's official notice, that stretch closed to all traffic, 24 hours a day, seven days a week, starting June 29, 2026, to allow the culvert work to proceed. The project is meant to fix drainage infrastructure and extend the road's long-term reliability. As of the town's most recent posting, no reopening date has been announced.

A few things worth knowing if you're planning around it:

• The closure covers Route 117 specifically at Old House Lane, not the entire route through town.
• Work began with utility relocation, including moving Con Edison gas lines, before the full closure took effect.
• The town has posted detour routes through its alert system, which is worth checking before a drive rather than after you're stuck in it.
• If your normal route to the park or downtown runs through that stretch, this is the season to have a second way in mind.

It's a small, temporary disruption to the road network. It's also a decent nudge toward using the trail network instead, at least for the trips short enough to walk.

The Park You Thought You Knew

Gedney Park was never just the pond loop. It was built in pieces, purchased in two separate deals four years apart, and expanded over decades into three distinct sections that most visitors experience as one. The trail data backs up what the layout suggests: there's a full outer loop, a set of blazes that actually work if you follow them in order, and a connection to two longer regional trails that most people driving past the entrance never think to use.

None of this changes what Gedney Park is for. It changes how much of it you've actually seen.

If a summer spent rediscovering your own neighborhood has you thinking about what's next, whether that means more outdoor space, a shorter walk to the trailhead, or simply a different part of town altogether, The E&F Team knows Chappaqua and the surrounding towns well enough to talk through what that next move could look like.
