Herkimer Collecting - Quick Directions Page

A public service project always open to input  from the community interested in Herkimer diamonds.
There is no real contact although Margaret Hasting's daughter Linda lives at the site. The surest way not to get messed up is to exit the NY Turnpike at Fonda. Go West to the bridge and cross the river. Turn left on Rt 5. Go West to the first road out side of Fonda that goes up the hill. This is Hickory Hill Road. It is not
a right turn but angles up the hill. Follow Hickory Hill for several miles until you come
to Barker Road. Turn right on Barker. This road curves around and comes to Stone
Arabia Road. Turn left on Stone Arabia. The first driveway to the left is the entrance to the mine. The alternate route is to go through Palatine Bridge and take Rt 10 North to Stone Arabia Road and turn East for several miles. Look for Barker Road
(which becomes England Road on the North side of Stone Arabia) Then go back to
the mine.The only sign to the mine is a crossed pickaxe and shovel painted blue near the entrance. But even that was overgrown last summer, thus the Barker
Road directions. (directions taken  from the link below)
