Jones Island State park is a 188-acre marine camping park with 25,000 feet of saltwater Shoreline
on the San Jaun channel. The park features a beautiful loop trail down the center of the island then around the western shore.The park has 24 primitive campsites. Two of the sites are part of the Cascadia Marine Trail and strictly reserved for those arriving by human- or wind-powered watercraft.A herd of black-tail deer live on the island. The deer have become habituated to the presence of humans and are quite tame. Visitors often feed the deer resulting in their becoming dependent on handouts of unnatural foods and potentially dangerous interactions between wild animals and humans. Feeding wildlife is prohibited by law in State parks. Violators may be fined and evicted.
