The Sands Point Preserve Conservancy is a non-profit 501(c)(3) organization responsible for preserving the legacy of the historic Guggenheim Estate and ensuring its vitality and relevance today.  From maintaining the 216-acre grounds, to making necessary repairs to Hempstead House and Castle Gould, to providing innovative community programming, the Conservancy works each day to protect this historic and natural gem.

We cannot do it without you. 

When you make a donation or purchase a daily pass, annual Membership, event ticket, or sponsorship package, you provide significant support to our mission.  When you come to hike the trails, picnic by the pond, bring your children to the playground or your dog to the dog park; when you tour our mansions, attend a seasonal event, or educational class; when you step foot onto this estate, you give it life.

We hope you’ll consider all the ways to give to the Sands Point Preserve.  For more information, contact Melanie Dunbar, Development Manager, at 516-570-2236 or
