Legacy & Stewardship

Nearly a Century of Family History

The story of the Island House Estate begins in the 1870s, when the Adirondack wilderness first attracted families seeking respite from city life. The property passed through the hands of the Wickes family, then the VanSlyke family from 1892 to 1920, before the Schultz family acquired and transformed the estate beginning in 1942.

For more than eighty years, the Schultz family invested not only in the structures themselves but in the land—the trails, the shoreline, the equestrian facilities—creating one of the most storied private estates for sale in the Adirondack region. What is offered today is not simply a property, but a legacy of sustained, devoted stewardship.

The Adirondacks are the greatest treasure of the northeast — wild land that makes wild men free.
