The Holbrook Island Sanctuary State Park is a state park and recreation park in Brooksville, Maine. It is best noted for its scenic natural areas and the fact that it is a lesser known park.

The top draw that people come for in the Holbrook Island Sanctuary State Park is its natural scenery. It is usually ?marketed? for the opportunity of getting leisurely walks through dark stands of softwood and clearings that were once a part of an estate. It also features a portion of the Penobscot Bay, offering a shore that is just what people think of when the name of the state of Maine is mentioned.

Among the top recreational opportunities available at the site include canoeing, kayaking, birdwatching, cross-country skiing, fishing, hiking, snowshoeing, swimming, and wildlife viewing.
