Sitting along the banks of the Mississippi River and Lake Michigan, Illinois’s accessible location has for centuries made it an important hub. Historically emigrants from Mexico, Ireland and Poland would make the long journey over in search of work and a new home. Abraham Lincoln was among those who called Illinois home and the state honoured him by naming the small city of Lincoln after him – before he became president.

Most travellers booking flights to Illinois would probably pick Chicago as their city of choice for its renowned restaurant scene and shopping but there’s so much more to see in including 6,900 kilometres of shoreline and more than 50 state parks, making it one of the most scenic states in the US.
