2,611 named trails across 6,101 miles of mapped centerlines — every state-managed corridor and community-mapped path in the Adirondack Park, cross- referenced with trailheads, lean-tos, parking, and the peaks they climb. Use the map to get your bearings, then narrow the list by region, operator, or what the trail reaches.
O'Neil Flowage is a short 0.2-mile access route, likely connecting to a water feature or wetland area typical of Adirondack lowlands. At this distance, it's more of a spur or connector than a destination trail in itself. Expect minimal elevation change and a quick walk, possibly to a fishing or paddling put-in.
Observer's Trail covers 2.1 miles through terrain that lives up to its name—meant for watching, not racing. The moderate length makes it accessible for a half-day outing without requiring peak fitness. Expect a route that prioritizes viewpoints or natural features worth pausing for, though trail conditions and elevation gain will determine how much of a workout you're in for.
A very short connector in the St. Regis Canoe Area, the Ochre Pond Trail covers just two-tenths of a mile between the pond and nearby trail junctions. It's primarily used by paddlers portaging or hikers linking longer routes through this heavily watered wilderness. Expect a well-worn but straightforward path typical of the canoe area's portage network.
A modest woodland trail descends through mixed forest into a remote ravine where OK Slip Falls is reported to plunge more than two hundred feet in a dramatic cascade. The path, covering just over three kilometers, offers a tranquil approach to what many consider one of the more powerful yet secluded waterfalls in the region. The setting rewards those willing to make the descent with a quiet appreciation of Adirondack wilderness, far from the crowds that gather at better-known destinations.
Old # 4 Trail runs 1.2 miles through what was likely part of an earlier trail numbering system in the region, though its current designation and network aren't specified in available records. The short length makes it a quick out-and-back or connector, though without confirmed difficulty grading, expect typical Adirondack terrain—roots, rocks, and variable footing. Check locally for current trailhead access and whether it links to other maintained routes.
Old Bypass is a short connector at 0.2 miles, likely serving as an alternate route or detour around a section of trail. These brief bypasses typically reroute hikers around wet areas, eroded sections, or seasonal obstacles. Check local trail signs at junctions to confirm current routing and conditions.
Old Dam Trail runs just over a mile through terrain that likely takes its name from historical logging infrastructure once common across the Park. At 1.1 miles, it's a quick out-and-back or through-hike depending on access points, suitable for a short morning walk or as a connector to other routes in the area. Check local trail maps for current conditions and whether the old dam structure itself is still visible along the route.
A marked passage through the Adirondack backcountry, this trail extends roughly 3.3 kilometers under the stewardship of the New York State Department of Environmental Conservation. Yellow disk blazes guide hikers along what is understood to be a historic approach route, threading through terrain that reflects the character of the Dix Range wilderness. The path offers a quieter alternative to more trafficked ascents in the region, though conditions and maintenance levels can vary with season and weather.
Old Faithful runs 1.5 miles through terrain that doesn't match the Yellowstone geyser's fame but serves its purpose as a connector or access route in the network. The relatively short distance makes it a quick out-and-back or a linking segment for longer loops. Check local trail maps for current conditions and trailhead access, as shorter trails like this sometimes see less maintenance than major routes.
Old Farm Road covers less than half a mile through what was likely once cleared or agricultural land. The short distance makes it a quick connector or easy leg-stretcher rather than a destination in itself. Check local trail maps for current access points and whether it links to longer routes in the area.
Old Farm Road (Blue) covers less than half a mile through what was likely former agricultural land, now reverting to forest. The blue-blazed route is short enough for a quick leg-stretcher or access connector. At 0.4 miles, it's typically an easy walk on relatively level ground.
Old Farm Road Trail is a short, mile-long route that likely follows the remnants of a historic agricultural access road. The easy grade and modest distance make it suitable for a quick outing or as a connector within a larger trail network. At just over a mile, it's brief enough to combine with adjacent trails if you're looking for more mileage.
Old Forge Bridge appears in trail records as a named feature rather than a through-route, likely a connector or crossing point within the Old Forge trail network. With no recorded distance, this may be a reference node where other paths intersect or a short spur to a water crossing. Check local signage or recent trail maps for current routing.
A tenth of a mile connector or interpretive path, the Old Foundation Trail lives up to its name—presumably leading to or past the remnants of an old structure. At this distance, it's more of a short walk than a hike, likely serving as a historical curiosity or a quick side trip from a larger trail system. Check local trail maps or trailhead signage for context on what you're looking at and how it ties into nearby routes.
This approximate route traces what appears to be a former equestrian path, now less than a mile in length. The "approx" designation suggests the exact alignment may have shifted over time or that portions have become indistinct. At just over half a mile, it's a brief walk that likely saw more use in earlier decades when horses were a common means of accessing backcountry terrain.
This 0.1-mile connector sits along the historic Indian Pass corridor between the High Peaks and the lakes region to the west. At just a tenth of a mile, it likely serves as a brief link or alternate segment within the larger Indian Pass Trail system. Check current signage at the junction—short segments like this often clarify route options or provide access to nearby features.
This 1.1-mile route follows what remains of an old logging corridor, part of the network of resource extraction paths that laced the Adirondacks through the late 19th and early 20th centuries. Many such trails have since been absorbed into the forest floor or repurposed for recreation. Expect relatively gentle grades typical of working roads built to haul timber, though conditions vary widely depending on maintenance and recent use.
Old Lyon Mountain Trail covers 1.3 miles in the northern Adirondacks, near the former mining town of Lyon Mountain. The route leads toward the summit of Lyon Mountain, known for its fire tower and views across the Champlain Valley. Expect moderate terrain typical of shorter northeastern ascents—rocky sections and steady elevation gain through mixed forest.
This half-mile connector runs between the MacIntyre Range Trail and the Avalanche Pass Trail near Lake Colden, providing a shorter route for hikers looking to bypass Marcy Dam or adjust their loop options in the High Peaks Wilderness. It's a relatively minor path in a heavily trafficked area, often used by backpackers threading together different approaches to Wright, Algonquin, or Iroquois. At 0.5 miles, it takes about 15 minutes to walk and mostly serves as trail infrastructure rather than a destination itself.
This short connector runs less than a mile between the current Marcy Dam site and the newer bypass trail, part of the well-traveled High Peaks corridor south of Adirondack Loj. The original dam washed out in 2011, leaving an open meadow where the pond used to be, and this trail segment now provides an alternate route through that zone. It's typically combined with other trails rather than hiked on its own—a low-elevation link in a larger day hike or approach to the interior peaks.
The Old Northville-Placid Trail runs 1.8 miles as a historic connector segment, part of the longer 133-mile route linking Northville to Lake Placid. The trail sees light maintenance—mostly used by through-hikers completing the full NPT or as a day access into adjacent backcountry.
This 0.2-mile route follows what appears to be an abandoned woods road, likely a former logging or access track now used by hikers. The short distance suggests it either connects to a longer trail network or provides brief access to a feature or junction point. Its brevity makes it a quick walk, though without additional context it's difficult to assess terrain or current maintenance level.
This 2-mile unmarked route follows what appears to be an old roadbed, likely a former logging or access road now used informally for hiking. Without blazes or maintained tread, navigation relies on reading the corridor itself—look for the wider clearing, subtle grade, and remnant ditching that distinguish old roads from footpaths. Best suited for those comfortable with light bushwhacking and map work in areas where the route may fade or intersect with other unofficial traces.
Old Route 3 is a half-mile path that likely follows a former alignment of the state highway before modern rerouting. At 0.8 kilometers, it's a quick walk suitable for casual exploration or as a connector between points along the current Route 3 corridor. The old roadbed typically offers easy, level footing on what remains of the historic surface.
Old Route 30 is a half-mile remnant of the original highway alignment, now bypassed by modern construction. The short stretch offers a quiet walk away from current traffic, though historical context and specific landmarks aren't well documented in trail records. Best treated as a brief leg-stretcher or connector rather than a destination.
Old Rte 28 runs less than a mile through terrain that once carried highway traffic before the modern alignment was built. The short distance makes it more of a connector or historical curiosity than a destination hike. Because no current trail network or difficulty grade appears in the metadata, assume easy walking on what's likely an old roadbed.
Old Side Trail is a very short connector at one-tenth of a mile, likely linking two points within a larger trail network. At this length, it's more of a junction spur than a destination in itself. Its purpose is probably utility—reaching a viewpoint, a water source, or bridging two main routes.
This short connector runs less than half a mile through the backcountry, likely a remnant of winter recreation routes that predate newer trail alignments. At 0.4 miles, it's brief enough to serve as a quick link between longer routes or a turnaround option for those testing conditions. Expect minimal signage and a corridor that may still show evidence of its original groomed width.
