Portsdown hill runs from Bedhampton to the east and Fareham to the west. It is a chalk hill rising to about 360' above sea level. Most of the hill is a protected site as it is a valuable habitat for flora and fauna. Chalk is no-longer quarried from here but the site of the workings are now part of the beautiful walks. I have found the Little Blue butterfly here in large numbers (although only in the old quarry), Peregrine Falcons nest above the cliffs in the spring/summer, Buzzards and Kestrel soar on the thermals hunting for prey.
