From the glitter of Nashville, Country Music Capital and home of the Grand Ole Opry, to the Appalachia Mountains, Tennessee has many cultural, historical, and recreational activities for its visitors. Whether the vacationers' interests lean toward Elvis Presley's Grace land or Andrew Jackson's The Hermitage, Tennessee can offer something for every interest, including scientists who want to explore Oak Ridge, the "Manhattan Project," which is the first nuclear reactor and part of a World War II weapons project. The interconnected lakes of the Cumberland system offer fishing, boating, scuba diving, sailing, and water skiing. Other adventurers can go horseback riding, climbing, hiking, camping, and backpacking at accessible points along the Appalachia Trail and in the Great Smoky Mountains National Park. History buffs can retrace Daniel Boone's steps at theCumberland Gap, learn about Davy Crocket, and explore Civil War relics at Chickamauga and Chattanooga National Military Park. Vacationers, who enjoy urban settings, can visit museums and historical sites during the day and listen to country, soul, rock, and blues music at night in Nashville, Memphis, and Knoxville. Because many visitors to Tennessee drive through to points north and south, they find it a perfect state in which to leave the expressway and venture on Tennessee's historic Natchez Trace Parkway, the original footpath of the Chickasaw and Choctaw Nations
