The DOC Rotoiti / Nelson Lakes Visitor Centre is a Department of Conservation visitor centre on View Road in St Arnaud, at the gateway to Nelson Lakes National Park. The centre is staffed by DOC rangers, who give information on walks, tracks, weather, safety, hut and campsite bookings, and on heritage sites, cycleways, maps and marine reserves. The centre also shares local stories and history, and it covers the national park's walking tracks and those around Lake Rotoiti.
The website lists opening hours of 9am to 4pm daily. DOC's national network, which the centre's information covers, includes 14,000 kilometres of tracks, 10 Great Walks, 950 huts and 324 campsites. For someone heading into Nelson Lakes, the rangers' local knowledge of track conditions and bookings is the main thing the centre offers, and it is one of the places where visitors can plan a trip into the park.
