Parel Vallei

Parel Vallei is a suburb of Somerset West in the Western Cape, South Africa. There is a local high school, Parel Vallei High School.

There is a section of upper Parel Vallei road that is known as Spook Hill. On this section of the road it appears as if downhill actually is uphill and vice versa. It's an optical illusion best viewed in front of Straightway Head Country House, at the top of the Parel Vallei Road. Because it appears that cars roll uphill here, Spook Hill has generated discussion whether this apparent phenomenon is an optical illusion, is due to magnetism, or is one of the world’s great unsolved mysteries.
