Metacomet Trail
Blue blazed, as it is part of the New England National Scenic Trail, the Metacomet Trail consists of 62 miles of trail mostly in Central Connecticut. It goes by lakes and rivers, waterfalls and mountains, and is very rugged.
Read here about sections of it as (I try to!) run it:
Route 6 to Route 4 (Farmington)
