Marin Open Space Trust is a group of dedicated Marin residents who formed a non-profit land trust to raise private funds to help protect the last critical remaining open spaces in Marin.

We come from all walks of life, and we all share a deep and abiding love for this wonderful place we call home. We follow in the footsteps of pioneering Marin conservationists and leaders along with many, many other unheralded but equally devoted lovers of Marin’s natural lands
