Cleared for the Visual Approach [Runway] 24 in UNV. We had briefed the high terrain that we would fly over prior to intercepting the final approach course in the initial arrival briefing. We were proceeding directly to WOREX descending from 4;100 ft. to 3;100 ft. At approximately 3;800 ft. we got a terrain warning over the mountain. The Captain was the PF (Pilot Flying) and he added power and climbed to 4;000 ft. and the warning went away. We advised ATC and circled back around and completed the approach visually. GPWS warning. High terrain you fly over prior to intercepting the final approach course. Responded to GPWS. Climbed to a safe altitude. Stay higher over the mountain or if in doubt request the ILS to [Runway] 24 instead of visual.
First Officer reported responding to a GPWS while on a visual approach.
