The trigs of the Central Coast are found mostly in national parks, although a few remain in small reserves and suburban areas.
- There are only three trig stations in the coastal Bouddi National Park, which vary from quite easy (Bombi) to quite hard (Gerrin). Somewhat unusually for a trig point, both Gerrin and Bouddi are not at the highest points in the area.
- Many of the Brisbane Water National Park trig stations are local attractions: the Warrah Trig, Lyre Trig and Mount Wondabyne are the destination of three popular bushwalks.
- There are not many trig stations in Popran National Park, which is between the Pacific Motorway and the Hawkesbury River. They are generally hidden in thick bush and require some bushwalking and navigation to reach.
- Some of the hardest-to-reach trig stations lie in the rugged Dharug National Park. Although a handful are near bushwalking tracks or firetrails, many of them require a few hours of tough off-track bushwalking to reach
