Campsite 3 is a walk- and boat-access campsite on the eastern bank of the upper Noosa River, within Great Sandy National Park, roughly 15–19 km from Elanda Point by water.

It sits on the fringe of open forest and woodland featuring melaleuca, allocasuarina, bloodwood, and eucalypt, with open heathland plains to the east and plenty of shade throughout the site.

The sandy surface accommodates both walk-in and canoe or boat campers, and a jetty and picnic tables are provided on site. With a maximum capacity of around 13 people, it is the largest of the lower river campsites.

Campsite 3 also marks an important boundary: motorised vessels are permitted only as far as this point, with only non-powered or electric-motor boats allowed beyond.

It serves as the closest access point to the Cooloola Sandpatch walking track, which links back to campsites 1 and 2. No vehicle access permit is required to reach the site.
