What to know
Take the underground train from the terminal to Concourse C after security.

Airport layout
DEN has one landside building, Jeppesen Terminal, and three airside concourses: A, B and C. The underground train connects the terminal with every concourse.
Getting to the gate
The useful distinction at DEN is the airline's ticket-counter location and departure concourse, not a separate numbered terminal.
Connections
Concourse A is also walkable from the terminal bridge; B and C require the train.
