Hollyhock Hollow Sanctuary was the home and headquarters for Audubon International for 20 years, until the organization moved to Rensselaer Technology Park in early 2013. Located at 46 Rarick Road, Selkirk, NY, the sanctuary was the former estate of Leona and Robert Rienow, Ph. D. As a State University at Albany Professor and co-author of several books on government and the environment, Dr. Rienow was among early environmental advocates. Upon his death in 1988, the sanctuary was bequeathed to Audubon International and was converted into a preserve and public-use area for passive recreation.
With over 140 acres of natural beauty, hiking trails, and distinctive geology carved out by the Onesquethaw Creek, Hollyhock Hollow Sanctuary is a birdwatcher's paradise. About twelve miles from Albany, NY, the sanctuary serves as an outdoor classroom for the nearby schools, as well as a recreational space for cross country skiers, spelunkers, artists, and scout groups. Whether you are planning to explore the unique features of the area or are simply looking to take a long, quiet walk, visitors are welcome every day from dawn until dusk.
