Manganuku Campsite is a Department of Conservation campground set within Waioweka Gorge Scenic Reserve, easily accessed from State Highway 2 between Ōpōtiki and Gisborne.

The site sits beside the Manganuku Stream near its confluence with the Waioweka River, and is notable for its proximity to one of New Zealand's few remaining historic Howe truss bridges.

Native bush surrounds the camping area, and the river is well regarded for both swimming and fishing. The campground offers 20 non-powered and tent sites, with bookings required. Fires are permitted in designated fireplaces subject to any active fire bans.

The Little Manganuku Track begins nearby, climbing to a saddle overlooking the valley and offering views of a small waterfall and glow worms after dark.
