Cheap flights from Denver to Columbus from £154

When in Columbus with children, head to 333 W Broad Street to the COSI (the Centre of Science and Industry), one of the top 5 American children's museums. For $20, kids will have an admission to a dinosaur gallery with a mechanical T-rex, a space gallery with a replica space station to explore, and a high-wire unicycle ride.

Book buffs of Columbus gather in the Book Loft store on 631 S 3rd Street. You will see an old block of pre–Civil War-era buildings. And once you enter the store, you will get lost in 32 rooms filled with bestsellers, manga and others. Prices are also affordable.

Everyone knows the heart of Columbus intersects at Broad Street and High Street at the Ohio Statehouse. It is a must-see. But if you turn to less popular streets, like a nearby Old Country Line street, you will explore no less wonderful views and attractions. Purchase memorable jewellery with natural stones at Something Special Shoppe and then head to Olde Town Park.
