Holdsworth Campsite sits at the Holdsworth road-end in Tararua Forest Park, about 15 km west of Masterton via Norfolk Road and Mount Holdsworth Road.

Set in a forest landscape beside Atiwhakatu Stream, the campsite offers 150 unpowered sites and serves as the main trailhead for tracks into the Tararua Ranges.

Facilities include flush toilets, untreated tap water (boil before use), cooking shelter, and designated fire pits where campfires are permitted outside fire bans. Dogs on a leash are welcome. Bookings are required, and stays are limited to seven nights.

A DOC Campsite Pass is accepted. The surrounding area supports fishing, swimming, and walking. Nearby Holdsworth Lodge provides additional bunk accommodation for around 28 people.

The Atiwhakatu Track departs from the road-end, following the stream through mixed podocarp and broadleaf forest toward Donnelly Flat and beyond.
