Aircraft; Chart Or Publication; Procedure
I was the Pilot Monitoring on this leg. Upon the arrival into the terminal area; Bangor Approach was giving us radar vectors for the ILS 33 approach. We were eventually told turn to a heading of 360 and to maintain 2500 feet until establish [and] cleared for the ILS 33 approach. At the time; we were in between CUVOT and ELSUH still on the assigned heading when we received a 'terrain terrain; pull up' with a ground proximity caution message on the PFD. The captain proceeded with a go-around procedure. I contacted ATC and we were given a heading and altitude to fly. We then performed all necessary procedures to come back around and land safely. We asked ATC what the possible cause of the alert was and he then advised us that his minimum vectoring altitude was 2100 feet in the area (we were at 2500) and that he has seen it happen before to aircraft due to a hill between CUVOT and ELSUH. Escape maneuver followed by an uneventful landing and arrival to the gate. Request to join the localizer at a higher altitude in IMC conditions
