This small community is located in Lane County, 6 miles southeast of Cottage Grove (Exit 174 off of Interstate 5), between Ganging Station and Gulp Creek along Primary Forest Road 17. Dorena is also situated within the Umpqua National Forest, just southeast of Dorena Reservoir (part of the Eugene-Springfield, Oregon metro area).
Three parks in the area offer many Outdoor Activities including: Boating, swimming, sailing, fishing and water skiing.
Located at the upper end of Dorena Reservoir, the Dorena Covered Bridge was built in conjunction with the completion of Dorena Dam. Sometimes referred to as Star Bridge, it offers access to the nearby Star Ranch. Star Ranch was once a large private estate that has been reduced to about 100 acres. The original town site, named for Dora Burnette and Rena Martin (by combining parts of their first names), is underwater at the bottom of the reservoir.
