Description
Arcos de la Frontera sits dramatically on a sandstone ridge overlooking the Guadalete River valley. The town has a medieval fortress and many interesting religious buildings from c. 11th-15th centuries on top of the hill and these are obviously a hotspot for tourists who enjoy the narrow winding streets, carved stonework, and excellent views over the surrounding countryside.
Looking up, expect to see Lille Tårnfalk, and try to distinguish between Gråsejler and Mursejler which both have colonies here. At the viewpoints, look down onto the impressive limestone cliff-face for Allike or possibly a Kirkeugle and look out for Gåsegrib, Dværgørn or Hvid Stork flying nearby.
Below the town is the Guadalete River and a small reservoir both of which have tracks or roads from which they can be viewed. These are home to waterfowl and riparian species as well as many warblers. Ensfarvet Stær is common, Silkehejre Fiskehejre are likely. Purpurhejre and Sultanhøne both apparently breed in the vicinity and in the summer it can be a good place to see Sydlig Nattergal.

Access
Arcos de la Frontera is located in the province of Cádiz in Andalusia, about 35 km east of Jerez de la Frontera. Parking is available near to the viewpoint at the top of the hill, however it can be very busy with both tourists and residents. The streets are rather narrow and it can be difficult to manouvre a large car. Other parking is available a little down the hill.
