Good for a change of pace ride, its not very big and there is some hike-a-bike sections you will need to deal with. There are marked trails, just follow the loop, some great look out points on the blue trail.
From middletown Rt 9 get off at Rt 82 and head east. cross East Haddam bridge, continue on 82. at Hadlyme 4 corners take left (keeping on 82) Take right at Gungy Rd. (just before Rt 11, Ice Cream shop there on the right) at fork bare right, turn left then a quick right to stay on Gungy Rd. park is about 2 miles down on left.
