I have lived in and around Marietta my entire life. At 36 years old, I have seen just about every part of the city, but the most astonishing part of the city is the square. Marietta Square is the seat of government in the county, and it is one of the best tourist attractions outside of Atlanta. Marietta is right on Interstate 75, and that road goes all the way from Miami to Canada. Therefore, you can pass right through the city just after you get off the highway.
Marietta is famous for the The Big Chicken. The Big Chicken is a KFC restaurant that has a large chicken built on top of it. It has been there for decades, and people even give directions based on The Big Chicken. Six Flags is about 20 miles south of Marietta, and a water park called White Water is just down the road from The Big Chicken.
Marietta has a rising food scene where discerning chefs are making everything from authentic Mexican cuisine to haute cuisine in their kitchens. Also, there are many homestyle restaurants that offer the best of soul food from down south.
Marietta is a suburban city that has many people working down near Atlanta during the day. However, it is far away from the city so that you do not feel like you are in the middle of the city.
Marietta is a great place to stay because it gives you a little bit of everything without putting you in the middle of downtown Atlanta. The town itself is its own capital in Cobb County.
