The spit is part of Fort Casey State Park, which is an interesting combination of early settlement, construction of coastal defense facilities in the early 1900's, attempts to link the mainland with a railway system, and later attempts of real estate development resulting in controversy leading to the preservation of the area.
Keystone Spit remains largely undeveloped, and, along with Crockett Lake, provides habitat for migrating birds.
Two roads along the spit offer convenient access to the beach.
