The easiest approach is from the Thruway traffic circle at the intersection of Route 28, the NYS Thruway (I87) exit 19, Colonel Chandler Drive (I587) and Washington Avenue.
From the Thruway traffic circle, take Colonel Chandler Drive for about 1 mile to a major intersection with a stoplight. Proceed through the intersection and bear slightly left onto Broadway. Follow Broadway for about a mile, passing under a railroad bridge. Turn right on Cedar Street (just past Ulster Performing Arts Center -UPAC). Then turn left on Iwo Jima Lane, and left on Greenkill Avenue. The building is on the left.
