The sanctuary provides amazing coastal vistas from the parking area and is a hot spot for butterflies and seabirds at particular times of the year. In the fall, migrating monarch butterflies may be seen. Throughout different seasons, look for shorebirds, loons, sea ducks, and other coastal birds in Gloucester Harbor and the Atlantic Ocean. Although the sanctuary does not have a formal trail system, the coastal view is worth the visit. Parking is limited to our lot at the lighthouse. Just a short walk up the road from the parking area is the entrance to the Eastern Point woodlands, which provides a short loop trail through deciduous forest. The woodland entrance is across from a cul de sac named Aileen Terrace. Trails may be wet in spring.
