Island Alliance promotes the use, enjoyment, and awareness of the Boston Harbor Islands national park area by creating vibrant public spaces, facilities, and programming on the islands, raising and managing the public and private resources necessary to do so.

As the sole organization designated in the Boston Harbor Islands Park Partnership model to raise dollars for the Park, our energies are devoted to attracting resources and revenues for the Park projects and programs, including historic preservation, scientific research, island-based curriculum, and youth mentoring programs--and sponsorship of events that bring the public to the island free of charge.
