Bolon Island is a quiet place with a hiking trail that goes halfway around the island. Since 1988 the shoreline on the Umpqua River side has hosted hundreds of double-crested cormorants, each pair building a stick platform in the trees. Rookeries like this are usually too remote for easy viewing, which makes this day-use area unusual. The trail also offers views of the Umpqua River. The park has no restrooms or drinking water.
