Towards the Pass of Michmos. The Philistines were camped in Michmos, and Michmos was on a mountain. Yisroel was in a city named Geva, and Geva was also on top of a mountain, and those two mountains were opposite each other. The valley was between them, as is stated in this episode, "and the Phillistine garrison went out toward the Pass of Michmos," which is on the side toward Geva, to the valley between them.
