The 2,686-hectare (6,640-acre) national park is situated approximately 90 kilometres (56 mi) south of Melbourne on the Mornington Peninsula.

Together with the adjacent Arthurs Seat State Park, the national park was listed on the now-defunct Register of the National Estate, in recognition of their outstanding values and their importance as part of the protected area's heritage.

The walk features a network of cliff top tracks with spectacular ocean views and dense coastal vegetation, as well as sections of long beach walks which pass by sculpted sand dunes and tidal rock pools.

[2] The Farnsworth Track links Portsea Surf Beach with London Bridge and is 2 kilometres (1.2 mi) in length.

Surrounded by farmland, the area contains a variety of vegetation communities, making it a wildlife haven and excellent place for nature walking.
