The greatest concentration of state parks in Oregon is found along Highway 101. They have preserved old-growth forests and historic sites, as well as provided recreation, including camping and picnicking. The most-popular campgrounds have sites that can be reserved by calling up to 11 months in advance.
Originally part of the Highway Department, the Oregon State Parks and Recreation Department was given its independence almost two decades ago. As part of ODOT, the parks were at one time the beneficiary of gasoline tax money, but Oregon voters decided that all gas taxes would go only for highways and the parks were given an unstable status, dependent on the general fund appropriation from the legislature every two years. More recently, funding has increased and stabilized and OPRD is again opening some new parks.
