8 Trails In Upstate New York With Abandoned Ruins Hiding In The Woods

Somewhere out there, an old stone wall or a crumbling foundation is just sitting in the middle of the woods, waiting for someone to stumble on it mid-hike.

Eight trails scattered through Upstate New York deliver exactly that, mixing regular forest scenery with the kind of abandoned structures that make you stop mid-step and wonder who lived there.

Nature’s clearly been working overtime on these ruins for decades. Vines crawl up brick that hasn’t held a roof in generations.

Rusted machinery sits half swallowed by moss, left behind by whoever walked away last. Nobody posts signs explaining the history at most of these spots, which somehow makes the discovery feel more real.

Eight trails, each with its own quiet mystery buried a little further down the path than you’d expect.

1. Doodletown Trail — Bear Mountain State Park, Tomkins Cove, NY 10986

Few places carry as much quiet history as Doodletown, a former settlement that dates back to the mid-1700s.

What was once a living, breathing community is now a forest floor covered in stone foundations, old wells, crumbling steps, and at least one cemetery that will genuinely stop you in your tracks.

Doodletown became part of Bear Mountain State Park, and most of its buildings were cleared out by park workers during the 1960s. The address you want is Tomkins Cove, NY 10986, right inside the park boundaries.

The trail system here is well-marked and manageable for most hikers.

What makes this spot different from your average ruin trail is the sheer density of remnants. You are not looking for one crumbling wall.

You are walking through the skeleton of an entire neighborhood. Stone church ruins, house shells, and old garden terraces appear around nearly every bend.

The forest has moved in fully, which makes the whole experience feel like stumbling onto a movie set that nobody cleaned up. Bring water, wear layers, and give yourself at least two hours to actually absorb what you are seeing.

Bear Mountain State Park surrounding Doodletown offers additional trails that extend a half-day outing into a full one.

The combination of Revolutionary War history and abandoned settlement ruins makes this corner of the park genuinely unlike anything else in the Hudson Valley region.

2. Sterling Lake Iron Works Loop — Tuxedo, NY 10987

Sterling Lake Iron Works is one of those places where history hits differently when you realize the machinery stopped over a hundred years ago. The iron ore operation here ran from 1751 all the way to 1891, which means these ruins have been quietly aging for well over a century.

The loop itself covers about 4.2 miles and passes through some genuinely beautiful terrain alongside Sterling Lake.

You will find old stone structures, blast furnace remnants, and the kind of industrial bones that remind you New York was once a manufacturing powerhouse long before skyscrapers existed.

The trailhead is accessible from Tuxedo, NY 10987.

Hikers with kids will find the loop manageable, though the terrain does have some uneven sections near the ruins themselves. The lake views along the way make the whole outing feel like a two-for-one deal.

You get solid scenery and a full history lesson without paying admission. The iron works ruins are surprisingly well-preserved given their age, and the forest setting around them adds a layer of atmosphere that no museum could replicate.

Go on a weekday if you want the place mostly to yourself.

Tuxedo sits just an hour north of New York City, making Sterling Lake one of the most accessible industrial ruin experiences available to weekend hikers who want serious history without a long drive or an overnight stay anywhere outside the metro area.

3. Catskill Mountain House Site (North-South Lake Trail) — Haines Falls, NY 12436

There was a time when the Catskill Mountain House was considered one of the most fashionable places in all of America. Presidents stayed there.

Artists painted it. Then the years rolled by, and the grand hotel was eventually demolished in 1963, leaving only its foundation behind on the ridgeline.

The North-South Lake Trail brings you right to that foundation, which sits at a dramatic overlook above the Hudson Valley. The address for the campground and trailhead area is Haines Falls, NY 12436.

From the parking area, the walk to the site is steady but very doable for most hikers of reasonable fitness.

Standing on the old foundation and looking out at the same view those 19th-century guests once admired is one of those genuinely powerful trail experiences. The forest has filled in around the edges, but the clearing at the site still opens up to a sweeping panorama.

On a clear day, you can see for miles. The ruins themselves are modest compared to the grandeur the hotel once represented, but that contrast is exactly what makes the visit stick with you long after you have driven home.

The Hudson River School painters who immortalized this ridgeline in the 19th century were responding to the same view available from the foundation today.

Standing where Thomas Cole once stood and looked gives the hike a specific cultural resonance that most trail experiences simply cannot offer.

4. Rochester Hollow Trail — Rte 28, Big Indian, NY 12410

Rochester Hollow is the kind of trail that rewards the curious. Farmers once carved out a working community here in the Catskills, and the evidence of their effort is scattered across the entire route in the form of stone fences, old foundations, and overgrown field boundaries.

A mountain brook runs alongside the trail for much of the walk, which makes the whole experience feel more like a stroll through an outdoor gallery than a typical hike. The trailhead is accessible from Route 28 near Big Indian, NY 12410, and the terrain is relatively gentle compared to other Catskill routes.

What really sets Rochester Hollow apart is the way the stone fences just keep appearing. You will round a bend expecting forest and instead find a long, carefully stacked wall that someone built by hand generations ago.

The craftsmanship is remarkable given the rugged landscape. The brook adds a soundtrack to the whole thing, which is a nice bonus.

Pack a lunch and find a flat rock near the water for a proper break. The trail is not heavily trafficked, so you get the rare pleasure of hearing actual nature instead of other hikers talking loudly into their phones.

The Big Indian area of the Catskills sits in Ulster County along the Route 28 corridor, a stretch of road that passes through some of the most authentically rural mountain scenery in the entire region.

The hollow rewards hikers who slow down enough to notice the details that faster visitors miss completely.

5. Franny Reese State Park Trail — Haviland Rd, Highland, NY 12528

Franny Reese State Park is one of those places that most Hudson Valley residents have never actually visited, which means you get to feel like you discovered something.

The park sits above the Hudson River and holds the ruins of a 19th-century estate that has been slowly returning to the earth for decades.

The trail covers about 2.5 miles and offers views of the Mid-Hudson Bridge through the tree line, which is a genuinely striking combination of old and modern. The park entrance is on Haviland Road in Highland, NY 12528.

Parking is available and the trail is accessible without any technical gear.

Along the route, you will pass stone walls, old building foundations, and scattered remnants of what was once a refined private estate. The Hudson River views alone are worth the trip, but the ruins add a layer of intrigue that elevates the whole outing.

The trail is not very long, so you can complete it comfortably in under two hours. Bring a camera because the combination of crumbling stonework, forest light, and river views creates some genuinely compelling compositions at almost every turn on this trail.

6. Pratt’s Rock Trail — Main St, Prattsville, NY 12468

Pratt’s Rock is genuinely one of the strangest and most fascinating historical sites in all of New York, and that is not an overstatement.

A leather tanning tycoon named Zadock Pratt commissioned stone reliefs to be carved directly into a hillside starting in the 1840s, essentially creating his own monument while he was still alive.

The carvings include portraits, a horse, a hemlock tree, and other personal symbols that Pratt wanted preserved for posterity. The trailhead is right off Main Street in Prattsville, NY 12468, making it one of the most accessible entries on this entire list.

The hike to the carvings is short and steep but very manageable.

Once you reach the rock face, the carvings come into view and the whole thing just clicks into perspective. This is not ruins in the traditional sense, but it is absolutely a relic of a very specific and eccentric personality from American history.

The surrounding forest and hilltop views add to the atmosphere considerably. Prattsville itself is a small Catskill town worth a brief wander before or after the hike.

The whole excursion, including drive time from nearby towns, makes for a very satisfying half-day adventure.

7. Blue Mine Trail — Harriman State Park, Sloatsburg, NY 10974

Blue Mine Trail punches well above its weight for such a short outing.

The trail leads through Harriman State Park to the ruins of an actual 19th-century iron mine, and unlike many historical sites that have crumbled beyond recognition, the structures here are remarkably intact.

You can see original stone walls, mining infrastructure, and the mine entrance itself, which gives the whole site an immediacy that longer, more famous trails sometimes lack. The trail is accessible from Sloatsburg, NY 10974, within Harriman State Park.

Parking and trail access are straightforward for most visitors.

Harriman is already one of the most beloved parks in the New York region, but Blue Mine adds a specific destination that gives the hike a clear payoff.

The mine was part of the broader iron ore industry that once defined this corner of the state, and standing at the entrance, you can genuinely feel the weight of that industrial past.

The trail itself is short enough that you can combine it with other Harriman routes for a fuller day out. Wear sturdy shoes because the terrain near the mine structures can be uneven and a bit rocky underfoot.

8. Delaware & Hudson Canal Trail — High Falls, NY 12440

The Delaware and Hudson Canal Trail is the flat, easy option on this list, and it earns its spot without any apology.

Built in 1828, the canal was an engineering achievement that moved coal from Pennsylvania to New York markets, and the ruins along this trail are some of the best-preserved canal infrastructure in the entire Northeast.

You will walk past original lock chambers, stone walls, and aqueduct remnants that are still standing after nearly two centuries. The trail runs through High Falls, NY 12440, a small town that is worth exploring before or after your walk.

The terrain is gentle enough for most fitness levels.

What makes this trail particularly satisfying is that the ruins are not just piles of rubble. The stonework is recognizable and the canal structure is legible, meaning you can actually picture how the whole system functioned.

That clarity makes the history feel accessible rather than abstract. The surrounding woods and nearby creek add natural beauty to what is already a historically rich route.

High Falls itself has a charming small-town character that pairs nicely with the trail experience, so budget extra time to poke around the village after your walk is done.

High Falls has developed a quiet reputation as one of Ulster County’s more charming small stops, with independent shops and a historic inn that make lingering after the trail feel completely natural.

The canal ruins and the village together create an afternoon that covers history, scenery, and good food without any effort.
