The park consists of about 50 acres which wraps around the core part of the garden. It has evolved over the last few hundred years from a series of smaller mixed use enclosures into the open sheep grazed pasture of today. The large deciduous trees of English Oak and Sweet Chestnut dominate the mixed planting which also includes evergreen broadleaved trees and conifers.

Today sheep graze within a Higher Stewardship Scheme run by Natural England. This scheme requires a low fertility organic regime which helps to preserve the high biodiversity value of this old wood pasture system. Also within the HSS over 150 trees have been planted in the park to replace the rather elderly population many of which are 350 or more years old. 

Visitors are welcome to walk and take their dogs on leads into the park as long as the sheep aren't disturbed especially during lambing time. The views of St Austell Bay are spectacular and the Gribbin Daymark is clearly visible marking the entrance to Fowey Harbour. Special care must be taken as the ground is uneven and slippery in places and boots should be worn.
