The surface of this road has been gradually degrading over the past decade and some sections are now dotted with potholes but it's still reasonably drivable (with care) and there are plenty of opportunities to pull over the scan the marismas to the south or a series of large lakes between the road and river. The large numbers of Flamingos dotting the lakes are obvious but you need to look more carefully to pick out waders and the odd Marbled Duck (reduced to 13 pairs on the Coto Donana in 2022) hiding amongst the more numerous Red-crested Pochards. The scrubby marshes to the south conceal small birds including Spanish Yellow Wagtail, various larks and warblers but the prize here is Pin-tailed Sandgrouse. In my experience, one of the best places to look for this elusive species is the track near the Cortijo de Adventus.
