Motion Sickness: Denver to Aspen Drive

The Denver to Aspen road trip covers approximately 200 miles (322 km) and takes around 4 hours in normal traffic. The terrain is mountain highway, making it a very high motion sickness risk route.

Denver to Aspen via I-70 and CO-82 climbs through the Rocky Mountains to over 12,000 feet at Independence Pass. The combination of altitude (which independently causes nausea), tight curves through Glenwood Canyon, and the dramatic switchbacks of Independence Pass makes this one of the most motion-sickness-prone routes in North America.

Where Motion Sickness Hits Hardest

The sections most likely to trigger motion sickness are: Eisenhower Tunnel approach, Glenwood Canyon, Independence Pass (CO-82). Independence Pass is closed in winter - take I-70 to Glenwood Springs and CO-82 south instead. Altitude sickness compounds motion sickness above 9,000 feet. Hydrate aggressively before and during the drive.
