Dayuling is located at the intersection of Central Cross-Island Highway and Provincial Highway 14A. As the highest point of the Central Cross-Island Highway, Dayuling is typically considered as the dividing point of the highway into its west and east sections. To the west, the highway passes through a short one-way tunnel known as the Hehuanshan Tunnel (合歡山隧道) before descending to Lishan. To the east, the highway passes through Tianxiang before dropping into Taroko Gorge. Meanwhile, Highway 14A branches away to the south, climbing to its peak at Wuling.
