The Cambyretá Portal is one of the public access points to a scenic route that reaches inside the reserve. Leaving behind fields, tall grasses and marshes, the road takes visitors to the Park Ranger post after riding several kilometers.

Along the way, visitors can watch a wide range of birds, including the ochre-breasted pipit (Anthus nattereri), the sharp-tailed tyrant (Culicivora caudacuta), and the yellow robin (Xanthopsar flavus).
