Hop River State Park Trail is one of Connecticut's top rail-trails. Narrow cuts and a lush tree canopy make for enjoyable visits year-round. Most of the route, from the Manchester–Vernon town line to Hop River Road, follows a crushed stone surface. From the town line east to Washington Street, the trail is mostly forested. At Church and Phoenix streets, the trail branches north and is sometimes called the Rockville Spur or the Vernon Rails-to-Trails.
From the intersection continuing east on the Hop River Trail, the trail climbs gradually for a few miles past impressive rock outcrops. Beyond the Bolton Notch parking lot, the trail passes beneath State Route 44 and US 6, threads a narrow rock cut then descends several miles through thick woods. Past Steeles Crossing Road, US 6 comes into view on your left, but not so close as to break the mood. Keep watch for small waterfalls like the one near Burnap Brook Road, and enjoy the covered bridge over State Route 316.
Eventually, you pass beneath US 6 through a 100-foot lighted tunnel. Another mile brings you to Parker Bridge Road. Another mile brings you to Parker Bridge Road. The trail continues east toward Willimantic with one section of stone dust and the rest manageable but slightly bumpy dirt. After going under the US 6 bypass, the trail continues along the Hop and Willimantic rivers to end at Kings Road. Beyond Kings Road is a broken bridge that should not be used.
Vernon: The Church Street trailhead is just 1 mile south of Interstate 84 and located between Phoenix and Washington streets. To reach the Church Street trailhead from I-84 east, take Exit 65 and follow signs to State Route 30 north. Turn right at the first traffic signal on Dobson Road and cross beneath the interstate.

To reach the trailhead from Exit 66, bear right on Frontage Road, then turn left on Tunnel Road. After 0.25 mile, turn right on Warren Avenue. Drive 0.5 mile, take a left on Phoenix Street, then an immediate right on Church. Trailhead parking is on the right.
Bolton: Bolton Notch State Park; entrance is just west of where US 44 becomes Route 44/ I-384. Enter the park at the end of the guard rail heading west. Parking is also available at Steele's Crossing Road, about 0.3 mile west of US 6.
Andover: Park at Burnap Brook Road about 0.2 mile west of US 6 and on Wales Road about 0.2 mile west of US 6. From US 6 west, enter Andover, turn left onto Lake Road then right onto Merritt Valley Road. The road will intersect with the trail after about 0.2 mile.
