Devil's Hopyard State Park

Devil’s Hopyard State Park covers 1,000 acres in the quiet hill country of East Haddam, Connecticut, roughly 30 miles southeast of Hartford. The park takes its name from a long-debated piece of local folklore, and its character is shaped almost entirely by the Eightmile River, which cuts through a forested gorge and drops dramatically at Chapman Falls before continuing south through the valley. This is not a destination for beaches or open-water recreation. It is a place built around moving water, old forest, and the geology left behind by glaciers.

Chapman Falls and the Glacial Potholes

Chapman Falls is the reason most people come to Devil’s Hopyard. The waterfall drops more than 60 feet over dark traprock ledges in a series of steps, and the visual effect is striking in any season. Spring brings the heaviest flow, when snowmelt swells the river and the falls run loud and full. In summer the flow slows but the surrounding forest canopy fills in, making the area shaded and cool. Fall foliage frames the falls in color from mid-October into early November.

Directly below the falls, the riverbed is covered with circular potholes worn into the stone by glacial meltwater. These formations are unusually well-developed here, some several feet across and nearly as deep, and they give the park much of its geological interest. The state has installed a short viewing area near the base of the falls, but the rock surfaces stay wet and can be extremely slippery. Use real caution if you step off paved or graveled areas, especially after rain.

Trails Along the Eightmile River

The park has several miles of trails, most of them looping through second-growth hardwood forest and following the river corridor. The main trail network connects to Chapman Falls at multiple points and ranges from easy flat walking near the water to moderately steep terrain on the ridges above the gorge. Footing is generally good on the upland sections, rougher and rockier near the creek.

Fishing is permitted in the Eightmile River, which is stocked seasonally with trout. It draws a modest number of anglers in spring but is not a major draw for most visitors.

The trails are open year-round. Mud season in early spring can make some sections soft, and fallen leaves in late autumn can obscure rocky footing on steeper sections.

Camping at Devil’s Hopyard

The park has 21 tent campsites along the river, making it one of the few state parks in eastern Connecticut where you can camp inside the forest itself rather than at a larger managed campground. Sites are basic, with no hookups, and the setting is genuinely quiet. Pets are not permitted in the campground. The campground is open from early April through early October.

Reservations are recommended for weekends and strongly advised for summer holiday weekends. Camping fees are $17 per night for Connecticut residents and $27 per night for non-residents, plus processing fees. There are restroom facilities, but this is a tent-only campground with no RV accommodations.

Pet Policy

Leashed pets are welcome on all trails and picnic areas but are not permitted in the campground. The leash must be six feet or shorter. Owners are responsible for cleaning up after pets throughout the park. Given the tick populations in the area, it is worth checking dogs thoroughly after any trail walk, particularly during spring and summer.

Wildlife to Be Aware Of

Ticks are present throughout the forested trails and are most active from early spring through late fall. Deer ticks capable of transmitting Lyme disease are common in this part of Connecticut. Wear long pants and closed shoes when hiking, tuck pants into socks when moving through brush or tall grass, and do a full body check after any outing. Remove ticks promptly using fine-tipped tweezers.

Black bears live in the forests of eastern Connecticut and are occasionally seen in and around the park. They are generally not aggressive but are attracted to food smells. If you are camping, store food in a hard-sided cooler or bear-resistant container, never inside a tent, and do not leave anything scented, including cookware and trash, unsecured overnight.

Mosquitoes and biting insects are heavy near the Eightmile River and in the low wetland areas, particularly in May and June. Bring insect repellent. Long sleeves in the evening help as well. The problem diminishes considerably by midsummer but does not disappear entirely.

The rocky terrain near Chapman Falls deserves mention as its own hazard. Wet ledges and creek crossings can be genuinely dangerous, particularly for children. The mist from the falls keeps the lower rocks wet even in dry weather. Stay on established paths where possible and do not attempt to scramble up the face of the falls.
