West Bay Campsite – Jetty Zone sits at the eastern end of West Bay on the shores of Lake Rotoiti, within Nelson Lakes National Park.

It is reached by turning off SH63 about one kilometre west of St Arnaud and following Mt Robert Road; the entrance sits directly opposite the jetty. St Arnaud village is roughly a 3 km drive or 30-minute walk away.

The Jetty Zone is one of two camping areas at West Bay, the other being the Buller Zone to the southwest. The campsite is seasonal, open from late November through to the end of April.

Facilities include toilets, cold-water showers, freshwater taps, and a children's playground, with jetty and boat ramp access to the lake. No fires are permitted at any time.

The surrounding area offers several walking tracks, including the Brunner Peninsula Nature Trail along the lakeshore, the Anglers Walk beside the Buller River, and the Black Hill and Moraine Walks.

National Park by-laws apply throughout the campsite, and no domestic pets are allowed.
