This park is a quiet place with a hiking trail that extends half way around the island. The shoreline along the Umpqua River side of the park has been home to hundreds of Double Crested Cormorants since 1988. The birds nest close together, each pair building a platform of sticks in the trees. Such rookeries are usually too remote for easy viewing, which makes Bolon Island Day Use area so unique! The trail also provides a nice view of the Umpqua River.
