Rocky Glen State Park

Dayton Road, Sandy Hook, Newtown, Fairfield County, Connecticut


From US 84 heading east, get off at Exit 10. Turn right onto Route 34 east (Church Hill Road) and drive for a short ways and turn left onto Dayton Road. Follow the road to its end (a short drive) and park in the limited parking at the dead end by a house. You can see the trail marked with yellow diamond cut-outs.


hemlock grove, floodplain, marsh


In 1839 Charles Goodyear discovered the process for vulcanizing rubber at a shop in the glen in Sandy Hook, which gave rise to the American rubber industry and lead to the establishment of a rubber factory in Rocky Glen.


2/16/02.  The yellow-diamond trail takes you through a small valley and then up and over a ridge down to a small stream and then to a dam. The blazed trail stops here, but you can follow an unblazed trail along the stream to a second dam by the Fabric Fire Hose Company (for lease for business offices).

9/01/2005.  Dog Sonar and I parked just off on Dayton Road.  The trail was right in front of us.  The Newtown Trailway uses a blue arrow on a yellow diamond background.  A short walk brought us to the falls along the river.  Two streams meet here, one of them coming in from the north in greater quantity forming small waterfalls as they flow down the small drop. Farther along the trail there was an opening where we could reach the river.  We had to squeeze between the many stinging nettles to get to the river.  Another short walk down the trail brought us to an iron bridge over the river.  It is a little dangerous to cross the bridge because there are no planks on the road, just the iron skeleton itself.  I had to put my notes and field guide book into the back pack and then grab the dog with one hand, using the other hand to steady myself along the rail, and walk the iron rail very slowly one foot at a time.

As we neared the end of the trail, we saw a side trail off to the left.  There is a sign with an arrow saying "To Al's Trail".  I have no idea who Al is, but his white diamond trail heads up the rather steep ridge.  (We did not follow it.)

At the end of the trail, on the right, there is a marsh/wet meadow with New York ironweed in bloom among others. 

The path ended an the confluence with Farm Field Ridge Road.  We turned around and made the short trip back to the car.  Dr. Patrick L. Cooney.
