Starting our taxi in Denver; Ground Control gave us instruction to taxi to Runway 34L via F and WA. While taxiing on Taxiway F; my Captain asked for the Before Takeoff checklist. I was accomplishing the before takeoff checklist when my Captain commented that the aircraft ahead of us may have missed the turn to Taxiway WA. Not thinking anything of it; we continued to taxi on Taxiway F. When my Captain was about to turn to Taxiway WA; I commented and pointed to a direction sign in front of us that indicates that Taxiway WA is still straight ahead (arrow pointing up to WA). My Captain also saw the sign and decided to go forward as indicated by the direction sign. As we continued forward; my Captain and I realized that we actually missed Taxiway WA because of the misleading direction sign. The Ground Controller noticed that we did exactly the same thing as the previous aircraft that missed Taxiway WA. The Ground Controller then gave us another instruction to turn inside the WA deice pad and follow the next aircraft on WA. We then taxied on WA to Runway 34L without further incident.We believe that the direction sign just pass Taxiway WA is misleading. The direction sign should be placed just before the Taxiway WA right turn and the direction arrow should be indicating a right turn instead of a straight ahead arrow.
Air Carrier Pilot reported the taxiway signage is misleading at DEN airport.
