Idabel is located in southeastern Oklahoma in McCurtain County (of which it is the county seat) south of Broken Bow along U.S. Highway 259 and sandwiched between the Little River and the Red River near the Texas/Oklahoma border.
Idabel is known as the "Dogwood Capital of Oklahoma" for the tree's abundant presence here. It is also in the National Register of Historic Places for the Victorian-style Barnes-Stevenson House, with its 102-foot-tall oak tree, and the Magnolia Mansion, built in 1910. The nearby Museum of the Red River exhibits artifacts from both North and South American cultures with a special emphasis on the local Caddo and Chocktaw tribes.
