Cefn Tilla park was created in 1856 when the house and some land were bought for the second Lord Raglan.

The park is a long narrow strip of land lying mainly to the north of Cefn Tilla Court (nprn 36608). It is a landscape park in character with grassland and isolated trees, the ground rolling on a westward-facing slope with Cefn Tilla situated in a hollow. The park is bounded on the east by the Gwernesney-Llandenny road, on the west by field boundaries, and on the north by the minor road to Llandenny.
Until 1933 the Gwernesney-Llandenny road, now a public road, was the main drive but it is still partly tree lined. The main entrance now is at the southern end of the park and the tree-lined drive runs along the western boundary to the north side of the house. To the north a secondary drive crosses the park north-east/south-west from an entrance on the Gwernesney-Llandenny road.

Around the house are gardens (265955).
