There are two main roads linking the Experimental Forest and the outside world. Yen-chi Road(County Road 151 ), which connects the Chi-tou and Ching-shui-kou Tracts, joins Provincial Highway 3, which extends north to Nantou and Taichung and south to Touliu and Chiayi. Old Highway 21 (now called the Shui-li section of the New Central Cross-Island Highway), connects the Ho-she, Nei-mou-pu and Shui-li Tracts. It joins Provincial Highway 16 below Shui-li. Beyond Ming-chien, Provincial Highway 16 intersects with Provincial Highway 3. After Ho-she, the Shui-li section of the New Central Cross-Island Highway passes through the village of Shen-mu, Tsao-ping-tou. In Ta-ta-chia, it intersects with the Chiayi section of the Central Cross-Island Highway, which goes to Mount Ali and then to the city of Chiayi.

Within the Experimental Forest, most roads are small forest roads used to access different tracts and agricultural areas. Altogether, there are 78 forest roads with a total length of 370 kilometers. However, some forest roads have not been used for a long time because landslides and road collapse have made them impassable. On average, there are 9.18 meters of forest road per hectare. The Experimental Forest has such a high ratio of forest roads because it was established a long time ago. Thus, the transportation network is relatively convenient and fast.
