There are two car parks. One is along a track (leading to the ‘The Longhouse’ and ‘The Porter’s Lodge’) to the west of the site and is always accessible. The other is behind two pairs of normally-locked double gates and lies between the road and the main Observatory buildings. When the Observatory is open to the public this car park is open too. On special occasions, such as the South West Astronomy Fair, the grass areas are also brought into play.
