Piseco-Powley Road runs from Stratford to Piseco, along west of one of the last old Adirondack dirt roads. Home to many old growth Spruce trees -- many that almost touch the road. The West Branch of the East Canada Creek crosses Powley Road under the historic 1911 bridge.
It is located 8 miles south-west from where NY 10 crosses Piseco Outlet, and about 7.5 miles from where Piseco-Powley Road splits off from NY 10. From the south, Powley Place is located 10 1/2 miles north-east from Stratford, via Piseco Road.
There are four campsites located in the general victinity of Powley Place, which are part of the 22 designated campsites along Piseco-Powley Road.
