Including Stapledon Woods, the whole area covers 250 acres (1.0 km²) of which 13 acres (53,000 m²) are owned by the National Trust. The hill rises to 260 ft where there is a view-finder. From here there are fine views over the estuary of the River Dee to Hilbre Island and the Irish Sea. More distant views range to Snowdonia in the west and Blackpool and the Pennines in the east, more rarely as far as the Lake District to the north, and extremely rarely to the Isle of Man in the north-west.

The Mariners' Beacon stands nearby on the site of an old windmill, which was missed by mariners after it was destroyed by a gale in 1839. Consequently, the Trustees of the Liverpool Docks erected the Mariners' Beacon in 1841.

Calday Grange Grammar School is situated on Caldy Hill.
