Denver to Lawrence Road Trip: Epic Plains Journey

This 600-mile drive along I-70 from Denver, CO to Lawrence, KS traverses the High Plains, where the Rocky Mountain foothills give way to endless wheat fields. The route passes the geographic center of the contiguous US near Lebanon, KS, a fact often overlooked by travelers.

• Total distance: approximately 600 miles (965 km)
• Driving time without stops: 8.5 to 9 hours
• Primary highway: I-70 East from Denver to the Kansas Turnpike, then US-59 to Lawrence

The drive offers a unique cross-section of American heartland geography. From Denver's Mile High altitude (5,280 ft) to Lawrence's 866 ft, you'll descend gradually across the prairie.

Key stops include the World's Largest Prairie Dog in Oakley, KS, and the Eisenhower Presidential Library in Abilene. This how to find the best stops and hidden gems between cities guide will help you uncover more.

The landscape transitions from Colorado's shortgrass prairie to Kansas's tallgrass prairie. Near Junction City, the Flint Hills region offers rolling vistas of native grasses, a rare ecosystem preserved at the Tallgrass Prairie National Preserve.
