The Center at Mariandale sponsors retreats and programs covering various dimensions of spirituality and contemplative practices, including private, guided, directed, and silent retreats. The Center also welcomes nonprofit groups and organizations for day or overnight workshops, retreats, and conferences. Our guests enjoy the quiet, professional environment at the Center, as well as the beautiful, spacious grounds overlooking the Hudson River. The Mariandale Center is located 35 miles north of New York City in Ossining, NY, in the lower Hudson Valley. The Center is a 30-minute Metro-North train ride from Grand Central to the Croton-Harmon train station, and then a 5-minute taxi ride from the station.
