The Pachaug Trail is a 23-25 mile blue-blazed footpath traversing Connecticut's largest state forest across Voluntown, Sterling, Plainfield, and Griswold. With approximately 2,000 feet of total elevation gain spread across relatively gentle terrain, this makes an excellent introduction to overnight backpacking in New England. The trail winds through mixed hardwood and conifer forests, passing ponds, streams, Atlantic white cedar swamps, and the spectacular Rhododendron Sanctuary—a National Natural Landmark. Four primitive shelters provide overnight stops, making this ideal for a relaxed 2-3 day trip. Expect muddy conditions, stream crossings, and tick encounters, but also solitude and classic Connecticut woodland scenery. The trail can be extended by connecting with the Narragansett, Nehantic, and Quinebaug blue-blazed trails for longer adventures.
Backpack camping permits are required and available by reservation only through Connecticut DEEP. Submit your application at least 14 days before your trip. Contact the Eastern District Headquarters at (860) 295-2923 or email deep.eastdistrict@ct.gov. You can also mail applications to: Eastern District Headquarters, 209 Hebron Road, Marlborough, CT 06477.
Permits are issued for the four designated shelters only—dispersed camping is not allowed. Stays are limited to one night per shelter, and sites operate first-come, first-served among permit holders. The shelters are available year-round except during severe weather. No specific permit fee was published, so confirm costs when reserving.
Backpacking areas are located near public lands open to hunting. Exercise caution during deer hunting seasons (fall and winter) and wear blaze orange when hiking during these periods. Many areas of Pachaug State Forest permit firearms and archery hunting.
The optimal backpacking window is August through May, avoiding the peak heat, humidity, and intense bug pressure of June and July. Spring (April-May) offers blooming wildflowers and mild temperatures, though trails will be muddy from snowmelt and spring rains. Mountain laurel blooms in early summer. Fall (September-October) is arguably the finest season, with brilliant foliage, comfortable temperatures, lower bug activity, and drier trail conditions.
Winter backpacking is feasible with proper gear—the trail's gentle grades make it suitable for snowshoeing. However, gated forest roads close January 1 through March 31 annually (potentially earlier if severe weather hits), which may limit trailhead access. Roads reopen April 1.
Avoid late spring and early summer for overnight trips due to aggressive mosquitoes, black flies, and peak tick season. Connecticut's deer tick population is significant, and Lyme disease is a real concern from April through October.
Water availability is a major planning consideration. Hikers consistently report limited reliable water sources, particularly in summer when streams and small ponds may dry up or become stagnant. The trail passes numerous ponds and streams, but many are seasonal or unreliable. Great Meadow Brook Pond near Dawley Pond Shelter is one documented water source. Expect stream crossings throughout, though these are typically easy rock-hops except during high water from snowmelt or heavy rain.
Sections near Hell Hollow Pond and Locke Meadow Pond are low-lying and often flooded, especially during spring. Beaver activity creates dynamic water conditions. Treat all water sources—filter or purify everything.
For a 2-3 day thru-hike, resupply options are minimal. The southern terminus at Voluntown has Sunny's Supermarket (129 Main St, 860-376-3120), open Mon-Fri 6am-9pm, Sat-Sun 7am-9pm, offering groceries, deli sandwiches, and basic supplies. Griswold/Jewett City near the northern terminus has grocery stores but limited specific details. For extensive resupply, Pawcatuck has a Stop & Shop about 10 miles from the southern terminus. Voluntown is an extremely rural community—don't expect gear shops or outdoor outfitters. Plan to carry everything you need or ship a mail drop in advance to one of these small towns.
The primary hazard is deer ticks carrying Lyme disease. Tick encounters are near-guaranteed from April through October. Perform thorough tick checks daily, wear permethrin-treated clothing, and consider using DEET repellent. Ticks are active year-round during warm spells.
Stream crossings are frequent but generally not dangerous—expect to get wet feet year-round unless you're extremely careful. Footbridges exist over some brooks, but many crossings require rock-hopping. During spring snowmelt or after heavy rain, normally easy crossings can become challenging.
Mud is pervasive, especially in spring and after rain. Sections near wetlands and swamps remain muddy year-round. Waterproof boots won't keep you dry on this trail—embrace wet feet or plan careful footwork.
Hunting is permitted throughout much of Pachaug State Forest. Deer hunting with firearms occurs in fall and winter. Contact Connecticut DEEP for current season dates and wear blaze orange during hunting periods. Some hikers avoid the forest entirely during rifle deer season.
Navigation is generally straightforward with blue blazes, but some trailhead entrances (particularly the southern terminus) are unmarked. Download offline maps before starting. The extensive motorcycle trail network (58 miles of designated OHV trails) can be confusing—blue blazes are for hikers only; red arrows mark motorcycle routes.
Biting insects are intense in warm weather. Black flies and mosquitoes peak in late spring through early summer. Bring a head net and strong repellent for shoulder season trips.
Multiple trailheads provide access along the 25-mile route. The southern terminus is at Green Fall Pond in Voluntown, accessible via Breakneck Road near Lee Road. The northern terminus is on Spaulding Road in Plainfield. Over 22 parking areas exist throughout Pachaug State Forest, though specific Pachaug Trail access points include:
From major airports: Bradley International Airport (BDL) is the closest major airport, approximately 60-70 miles northwest. T.F. Green Airport (PVD) in Providence is similar distance. Shared shuttle services like CT Airlink and GO Airport Shuttle serve the general region but don't go directly to trailheads. Rental car is the most practical option.
Nearest towns: Voluntown and Griswold are small, rural communities. Jewett City (within Griswold) has slightly more services. No public transit serves the trailheads. Uber/Lyft operate in the area but availability is limited in these rural towns.
Roads are paved to most parking areas. Many interior forest roads are gravel but passable in regular vehicles. However, gated roads close January 1-March 31 (mud season), potentially limiting access during winter/early spring.
Book your shelter permit well in advance—the 14-day minimum application window is firm. Specify your intended shelters when applying. Since it's first-come, first-served among permit holders, have backup plans if your preferred shelter is occupied.
Shelter quality varies significantly. Dawley Pond Shelter sits beside scenic Great Meadow Brook Pond. Dry Reservoir Shelter is cramped with low clearance—no standing room. Peg Mill Brook Shelter (on the Narragansett Trail connector) has a metal roof and generous headroom. Scout reports before planning which shelters to target.
The Pachaug Trail connects with three other major blue-blazed trails: Narragansett, Nehantic, and Quinebaug. This allows creative loop hikes or extended trips. A popular option combines sections into a 28-mile loop within the state forest.
Highlights worth planning around: the Rhododendron Sanctuary boardwalk through Atlantic white cedar swamp (stunning in early July when rhododendrons bloom); Mount Misery overlook at 441 feet (short walk from parking area); and the Pachaug-Great Meadow Swamp National Natural Landmark.
Waterproof your gear thoroughly. Everything gets damp on this trail from stream crossings, mud, and humid forest conditions. Pack wet feet supplies: extra socks, foot powder, duct tape for hot spots.
This trail sees moderate motorcycle traffic on designated OHV routes—blue blazes are foot-only, but you'll hear engines in the distance. The forest also attracts mountain bikers, equestrians, and snowmobilers in winter.
Expect solitude compared to more popular New England trails. Pachaug State Forest's 26,477 acres provide genuine wilderness feel despite being in southern Connecticut. Don't count on cell service in the interior.
