Although this preserve is undergoing some construction still, their newest property overlooking Stony Brook Harbor is an expansion of the Costal Corridor trail and can be accessed through a pedestrian pass at Harbor Road. If you go far enough, you'll hit the LI sound! Parking is available off of Shep Jones Lane, and you can head out on any of the trails. You can even make a pit stop at Harmony Vineyards to grab a glass of wine ;)
Amazing place to explore some of LI's history. Aside from their very popular carriage exhibition, their upcoming 'Giants and Gems' exhibition will integrate the largest and the smallest works from the LIM’s Art and History collections, including fine arts, crafts, costumes, and household objects. Feel free to bring lunch and picnic outside to view some of the outdoor artwork also if the weather permits!
