The OC&E Woods Line State Trail is a rail trail in Klamath and Lake counties in the U.S. state of Oregon. It is Oregon's longest state park. The trail follows the old OC&E (Oregon, California and Eastern) and Weyerhaeuser railroads from Klamath Falls to Thompson Reservoir. Along its length it passes through the communities of Olene, Sprague River, Dairy, Beatty, and Bly. The OC&E Woods Line State Trail is paved from Klamath Falls to the community of Olene, approximately . Beyond Olene, the trail surface is graded and compacted, which attracts mountain bikers, hikers, anglers, equestrian users, and wildlife watchers. Additionally, the trail has a gentle 2 percent slope grade. History Construction on the OC&E Railroad (also known as the Klamath Municipal Railway) began in the summer of 1917 as part of a grand scheme to connect Central and Eastern Oregon with rail lines and take advantage of timber opportunities. Initial development efforts involved bonds sold by the city of Klamath Falls. Logging camps with spur railroads sprang up almost overnight, and by 1919, four lumber mills were located on the main line. After several delays, the OC&E was declared open in the fall of 1923, and in 1927 was extended to Bly. Southern Pacific and Burlington Northern (and their pre-merger railroads) operated the line jointly from 1925 until 1974, when it was purchased by Weyerhaeuser, who solely operated the entire railroad in support of its timber operations. At peak production in the late 1970s, the OC&E was reported to be transporting 35,000 loads of wood products a year. In the early 1980s, the OC&E had a decline in traffic, and when it was no longer cost effective to move logs by rail, Weyerhaeuser railbanked the line, and deeded it to the Oregon Parks and Recreation Department in 1992. The last logging train entered Klamath Falls on April 29, 1990. Uses The OC&E Woods Line State Trail is a conversion of the OC&E Railroad disused railway easement into a non-motorized path used for walking, cycling, jogging and horse riding. The now paved flat trails stretch through agricultural and forest areas appealing for recreational development. The OC&E linear park is used by over 130,000 visitors every year. For example, from Olene, an unpaved section of the trail passes ranch lands, rivers and forests. The trail provides connections to eight communities, five schools, and several suburban areas within Klamath Falls. Along each
