Great hiking area.
Hemlock George Reservation is located on the Charles River Between Newton and Upper Falls and Needham. To get there take Route 128(I-95) to Route 9 East and get at first exit (Newton Upper Falls). Turn right at stop sign onto Ellis St. and right again at next stop sign onto Chestnut St. Turn right at first traffic light onto Elliot St (Central Ave. in Needham). Parking is off of Hamilton Place (first right after crossing river).
