Directions from Hartford:
Take I-84 West to exit 33 (Rt 72 West). Take Exit 2 and make a right at the end of the exit onto Route 372 East. Turn left onto Metacomet rd. Go approx. .5 mile and you will reach a sharp curve in the road with a small pond on your left. Park in this area, but avoid parking in the vicinity of the “No Parking” signs to be friendly to the local neighborhood.
There is a Dirt Path at the middle of the bend that turns into a semi-paved road. Approach: Turn right into the woods once you've reached the large stacked cement blocks. This will bring you to the base of Pinnacle Rock. To get to the top of the mountain you can continue hiking past the large stacked cement blocks and turn right when you reach the first intersection on the trail.
