El Portal del Motoco — also called Puesto del Medio — is a rest stop and campsite situated roughly at the 42nd parallel, near the interprovincial boundary between Chubut and Río Negro.

It sits approximately 8 km from the trailhead at Balneario La Pasarela and is reached after about three hours of hiking through the lower valley of the Río Motoco (also known as Río Blanco), passing through dense Patagonian forest of coihue and Valdivian species.

The portal marks the halfway point on the full trek to the historic Camping del Motoco, which lies another 4–5 hours farther up the trail at roughly 15 km from the start.

The route follows the Río Motoco through its namesake canyon, with notably clear water running alongside the path. Day visits beyond the first footbridge require a fee; open fires are prohibited throughout the area.
