The flight path crosses the Bay of Biscay and passes over the Iberian Peninsula's interior. At cruise altitude (31,000-35,000 feet), you'll see the Atlantic coastlines of Ireland and Wales to the north, the Iberian Peninsula's interior plateau, and potentially the Sierra de Guadarrama mountains near Madrid if flying a more southerly routing. The Douro River valley may be visible during descent into Portugal.
