Appalachian Trail Connecticut

The Connecticut section of the Appalachian Trail, running 51 miles from the New York border at Schaghticoke Mountain to the Massachusetts border near Sage’s Ravine, traverses the finest hiking terrain in the state — the Taconic foothills and Housatonic Highlands of Litchfield County, passing through the Housatonic River valley, the dramatic St. Johns Ledges (the most famous rock scramble on the CT AT), the open ridge of Lion’s Head, and the deep hemlock gorge of Sage’s Ravine.

Connecticut’s AT section is justly celebrated for its variety — river-valley walking, rocky ridge traverses, waterfall gorges and open summit views — all within the short 51-mile corridor. The town of Kent (the AT passes through Main Street) and the villages of Cornwall Bridge and Falls Village are beloved trail towns. The Connecticut AT is a treasured natural icon of the state.

The Connecticut AT offers day hiking on the most celebrated sections (the St. Johns Ledges — a challenging rock scramble above the Housatonic River with dramatic river views; Lion’s Head — a 1,738-foot open summit with views across the Litchfield Hills and into New York; Sage’s Ravine — a hemlock gorge straddling the CT-MA border with a waterfall and crystal-clear brook; and the Housatonic Meadows section — a gentle riverside walk), multi-day section hiking (the full 51 miles can be hiked in 3-5 days with overnight stays at shelters), thru-hiking (as a section of the 2,198-mile Appalachian Trail from Georgia to Maine), fishing (the Housatonic River is one of New England’s finest trout rivers), and wildlife watching. The St. Johns Ledges, Lion’s Head and Sage’s Ravine are the signature destinations.

Fall (late September through late October) is the finest season on the CT AT — the Litchfield Hills hardwood forest turns brilliant gold and orange, the ridge-top views are sharpest in fall air, and the trail is at its most atmospheric. Spring (May–June) is excellent for the wildflowers on the forest floor and the returning warblers in the Housatonic corridor. Summer is warm but the forest shade is pleasant; the Housatonic is beautiful in summer. The St. Johns Ledges and Lion’s Head are finest in fall and clear spring days. Fall for the foliage and views is the highlight.

The Connecticut section of the Appalachian Trail was developed in the 1920s and 1930s, one of the original sections of the AT established by Benton MacKaye and the Connecticut chapter of the Green Mountain Club and later the Connecticut Forest and Park Association (CFPA). The CFPA, established in 1895, has maintained Connecticut’s trail network for over a century and continues to maintain the CT AT. The town of Kent and the Housatonic River valley were the homeland of the Schaghticoke and Mohican peoples, with deep Indigenous history predating the trail. The CT AT preserves a green corridor through the Connecticut Litchfield Hills that is a beloved hiking resource.

The Connecticut AT traverses the Taconic Highlands — a complex geological province of ancient Cambrian and Ordovician metamorphic rocks (schist, phyllite, quartzite and marble of the Taconic thrust sheets) that were pushed westward over the younger rocks of the Connecticut Valley during the Taconic orogeny. St. Johns Ledges is a dramatic quartzite outcrop above the Housatonic River. Lion’s Head is underlain by resistant quartzite. Sage’s Ravine cuts through the phyllite and marble of the Taconic sequence. The resistant quartzite and phyllite, the Taconic thrust sheets and the stream erosion created the varied terrain of the CT AT.

The CT AT corridor supports a rich highland wildlife community — black bears (increasingly common in the western CT Taconics; common near the trail), white-tailed deer, wild turkeys, ruffed grouse, and a breeding warbler community typical of Appalachian Highland forest (black-throated green, black-throated blue, Blackburnian, Canada, magnolia warblers and many others). The Housatonic River, which the trail follows in the Housatonic Meadows section, supports brown and rainbow trout, bald eagles (common in the river valley) and common mergansers. The CT AT is an excellent wildlife and birding corridor.

The Connecticut AT corridor is one of the most important wildlife and ecological corridors in Connecticut — a 51-mile strip of relatively undisturbed forest and ridge habitat connecting the New York border to Massachusetts through the western CT Highlands. The black bear population recovery in western Connecticut is partly dependent on this corridor. The Housatonic River is one of New England’s most important wild-trout rivers (with PCB-related fishing restrictions in the lower river). Protecting the AT corridor, the ridge and forest habitats, and the river water quality sustains the ecological significance of the CT AT.

The Connecticut Appalachian Trail holds a treasured place among the outdoor icons of Connecticut — 51 miles of the oldest and most famous long-distance trail in the United States, traversing the finest hiking terrain in the state, through the beloved Litchfield Hills and Housatonic Valley towns of Kent, Cornwall Bridge and Falls Village. The St. Johns Ledges, Lion’s Head and Sage’s Ravine are Connecticut hiking landmarks of the first order. The CT AT is a cherished natural icon.

The Connecticut AT is accessible at multiple trailhead parking areas along CT Route 7 (the Housatonic River corridor — the primary highway paralleling the CT AT, with trailheads at Housatonic Meadows State Park, the St. Johns Ledges, Kent, and other points) and CT Route 41 (for Lion’s Head and Salisbury). The AT passes through the Main Street of Kent (the only town on the CT AT where the trail runs through a town center). AT shelters are maintained by the CFPA (Appalachian Trail Conservancy guidelines apply). Check the ATC and CT DEEP for current trail conditions, shelter availability and regulations before any CT AT hike.

The Appalachian Trail Conservancy and the Connecticut Forest and Park Association (CFPA) maintain the CT AT and work to protect the trail corridor from development. Visitors help by following all Leave No Trace principles (pack out all waste, use established campsites and fire rings only, camp only in designated shelter areas), respecting all wildlife (especially bears — use bear bags at all shelters), staying on the blazed trail, and supporting the CFPA and ATC. The trail corridor, the wildlife habitats and the Housatonic River corridor are protected but vulnerable to development and overuse.

Black bears are increasingly common on the CT AT, especially in the Kent to Salisbury section — use proper bear bags at all shelters and make noise while hiking through the dense vegetation. The St. Johns Ledges scramble involves exposed rock faces (challenging, not technical, but requiring careful foot placement — use hands on the steepest sections and be cautious in wet conditions). Timber rattlesnakes are present on the rocky ridges (rare but documented — watch where you step). Ticks are prevalent throughout (check thoroughly after every day on the trail). Respect the bears, the rock scrambles, the rattlesnakes and the ubiquitous ticks.

The AT is free to hike. Camping only at designated shelter areas (no dispersed camping off-trail or off designated sites). Fires only in designated fire rings at shelters (check current fire restrictions — fires are sometimes prohibited). Bear bags required at all shelters. Hunting may occur adjacent to the trail corridor in season (wear blaze orange in fall). Dogs must be on leash in areas where required (check ATC for current dog rules). Fishing in the Housatonic River along the trail requires a Connecticut license; note PCB-related consumption advisories for the lower river. Check the ATC for current regulations and trail conditions.

The town of Kent (one of Connecticut’s finest small towns, with the AT on Main Street, excellent galleries, bookstores, the covered Bulls Bridge and superb restaurants), Macedonia Brook State Park (adjacent — the finest ridge hiking in CT), Kent Falls State Park (just north of Kent, with the finest waterfall in CT), the Housatonic River (excellent catch-and-release trout fishing), and the full Litchfield Hills of western Connecticut define the region. The CT AT corridor and the town of Kent anchor the outdoor and cultural experience of the western Connecticut Litchfield Hills, one of New England’s most rewarding hiking and small-town destinations.

Day hike the St. Johns Ledges from the River Road trailhead in Kent — 2.5 miles round trip to the dramatic quartzite ledges above the Housatonic River, the finest short hike in Connecticut. The scramble up the Ledges requires hands-on rock (trekking poles a hindrance here; stow them). Come in October for the Housatonic Valley foliage panorama from the Ledges — extraordinary. Day hike Lion’s Head from the CT Route 41 trailhead in Salisbury for the finest open-summit views in Connecticut, with an easy 3-mile round trip gaining 1,000 feet. Have lunch or dinner in Kent on any CT AT visit — the town is excellent and entirely worth the stop.
