Distance from downtown Buenos Aires: 70 km (45 miles), NE.
Main habitat of this area belonging to the National Parks system, is a grassland, seasonally flooded in part. Grassland can be both short or tall (in this case huge Pampas Grass), and wet parts vegetation includes thick grasses, reeds and cattail. There is little open water in ditches alongside the road. Patches of native forest add plant diversity attractive to a variety of songbirds.
Most of the birding here is along a 5 km long public, dirt road. Expect scattered traffic. Birding the road itself takes 3 hours average.
