mapquest will tell you guys to go down 84 then up 8 i believe, but the directions on the kent falls site take you on a nice scenic drive
From the East Hartford area: travel west on I-84, take Exit 39. Continue west along Route 4 to the intersection with Route 118 in Harwinton. Drive west along Route 118 to the intersection with Route 202 in Litchfield. Turn left onto Route 202 and travel west for about 7 miles to the intersection with Route 341. Turn right onto Route 341 and travel to the intersection with Route 7 in Kent, CT. Turn right (north) onto Route 7 and the park will be located approximately 4.5 miles ahead along Route 7.
I say all you MA people, and all the central or eastern CT/RI ppl meet up off exit 39
