Curiosity's landing site is Gale Crater; a location notable for having a large mountain of layered rock in the center known as Aeolis Mons (Mount Sharp). This prevents Curiosity from traveling directly across due to the steep incline towards the top. Instead, it was designed to drive up and along the shallower base.
