French Pass Campsite is a DOC-managed campground situated at the end of the long, winding, and partially unsealed Croisilles–French Pass Road in the Marlborough Sounds.

The remote location — roughly 70 km from the SH 6 turnoff north of Rai Valley — can also be reached by boat. The site offers 18 unpowered tent sites and serves as the gateway to Rangitoto ki te Tonga/D'Urville Island.

The campsite is well suited to boating, fishing, swimming, and kayaking, with visitors reporting sightings of dolphins and stingrays.

Advance online booking and payment are required prior to arrival, particularly during the peak summer season from late December through early February. A DOC Campsite Pass is accepted.
