Pea Ridge National Military Park
Perhaps the best-preserved Civil War battlefield in Arkansas, this 4,300-acre national historic site includes a seven-mile, self-guided auto tour road with 10 stops; a museum; trails; bookstore and visitor center. The March 7-8, 1862 battle was one of the largest fought west of the Mississippi, between 10,500 Union troops and 16,200 Confederate troops. The decisive Union victory ensured that Missouri would remain in Federal control. A marker at historic Elkhorn Tavern explains the Trail of Tears route (Elkhorn Tavern Segments) that went through the park; Trail of Tears National Historic Trail.
