Columbus is the capital and biggest city of Ohio, right in the middle of the state. It is a busy, friendly city full of colleges, science, and fun places to explore.
You can visit the amazing Columbus Zoo and Aquarium, splash at Zoombezi Bay water park, or explore hands-on fun at COSI, one of the best science centers in the country.
COSI is a giant science museum where you can touch, build, and experiment. Ohio State University also fills the city with students and cool events.
The Columbus Zoo is home to elephants, lions, and polar bears. Nearby gardens and riverside parks are great for a sunny day walk.
