The Long Pond Greenbelt is made up of more than 1,100 acres of interconnected ponds, woods, and wetlands that stretch from Ligonee Brook and Otter Pond in Sag Harbor to Sagg Pond and the Atlantic Ocean shore in Sagaponack. On this 3.5 mile walk with Dai, along the William B. Sickles Tree Identification Trail and the old Sag Harbor Railroad Spur Trail, you’ll have the opportunity to view some of these ponds ── Crooked Pond, Long Pond, Little Long Pond and Deer Drink ─and the ecological communities that surround them
