Stopover in Denver: what to do and when to leave
Denver International is far from downtown and its concourses connect to Jeppesen Terminal by train. The A Line makes Union Station possible on a long connection, but airport security and the rail return need a wide buffer.
With less than 9 hours, stay at DEN. From 10–12 hours, Union Station and LoDo can fit if baggage is checked through and at least three hours remain for the train, security and gate.
Your safety comes first. Reviewed on August 27, 2026 · Guidance, not immigration authorization.
