There are a handful of trig stations in Marramarra National Park, some close to walking but many on rugged and hard-to-reach ridges. There are many more trigs around the park, but these are often on private land or public access is not possible. A number of trigs in this area have also been destroyed over time.

Coba Trig in Marramarra National Park is reached via a route that's partly on a firetrail, and partly off-track. Only the stone cairn remains.
Remains of the original Ivory Trig cairn and the newer concrete pedestal are surrounded by scrub, above the Canoelands Ridge Trail in Marramarra National Park.
