Nelson Lakes National Park protects 102,000 hectares of the northernmost Southern Alps in New Zealand’s South Island. The park centres on two large glacial lakes, Lake Rotoiti and Lake Rotoroa, surrounded by beech forests, steep mountain ranges and alpine tarns. Visitors enjoy day walks, multi-day tramps, swimming and wildlife viewing from the gateway village of St Arnaud. Access is straightforward via State Highway 63, with the park lying roughly 100 kilometres from both Nelson and Blenheim.

About Nelson Lakes National Park
Nelson Lakes National Park lies in the northern South Island and protects a dramatic alpine landscape shaped by glaciers during the last ice age. Massive glaciers carved deep valleys now filled by Lakes Rotoiti and Rotoroa, the park’s two largest lakes. Steep mountain ranges, including the Travers and Spenser Ranges, rise above native beech forests that dominate the lower slopes.
The park supports rich biodiversity. Beech forests provide habitat for native birds including kaka, bellbirds, riflemen and the whio (blue duck). The Rotoiti Nature Recovery Project, established in 1997, has reduced predator numbers across approximately 5,000 hectares, allowing bird populations to recover and reintroductions such as great spotted kiwi to succeed.
European settlement began in the 1840s with grazing, followed by holiday homes and a hotel at Rotoroa by the early 1900s. The scenic values were formally recognised when the national park was created in 1956. Today the Department of Conservation manages the area for conservation and recreation, with strict biosecurity measures in place to protect the lakes from invasive algae.
Visitor experiences range from short lakeside strolls to challenging multi-day circuits. Facilities include the Nelson Lakes Visitor Centre in St Arnaud, campgrounds at Kerr Bay and Lake Rotoroa, and a network of huts and tracks. Water taxis operate on both main lakes.
Access and Facilities
The main entry point is St Arnaud on State Highway 63, a 1–2 hour drive from Nelson or Blenheim. A secondary road off State Highway 6 at Gowanbridge leads to Lake Rotoroa. Shuttle services and irregular bus options connect the area with nearby towns. The Nelson Lakes Visitor Centre provides track information, weather updates, hut bookings and advice from DOC rangers. Campgrounds, toilets and basic services are available at the lakeside settlements.
Hiking and Walking Tracks
Nelson Lakes National Park offers tracks for all abilities. Easy lakeside walks such as the Honeydew Walk and Bellbird Walk start from Kerr Bay and feature birdlife and honeydew beech forest. Moderate options include the Mount Robert Circuit with panoramic views over Lake Rotoiti. The popular Travers-Sabine Circuit is an 80 km loop taking 4–7 days through alpine passes, valleys and forests. Track conditions vary with season; snow, stream crossings and avalanche risk require careful planning, especially in winter.
Recreational Activities
Swimming is popular at Kerr Bay in summer, with a designated raft available. Kayaking and water taxis allow exploration of the lakes. Trout fishing is permitted in designated areas under Fish & Game regulations. Power boating is not allowed on the main lakes to preserve tranquillity. Mountain biking is restricted to formed roads within the park; nearby routes outside the boundary provide additional options. All visitors must follow biosecurity protocols to prevent spread of invasive algae between lakes.
Conservation and Ecology
The Rotoiti Nature Recovery Project, launched in 1997, focuses on predator control across 5,000 hectares of honeydew beech forest. Volunteers and DOC staff maintain trap lines, resulting in increased numbers of native birds. The park also protects culturally significant sites, including tapu alpine lakes such as Rotomairewhenua (Blue Lake) where entry into the water is prohibited. Ongoing efforts address wasps, deer, possums and invasive algae to maintain ecological integrity.
What Visitors Often Say

Reviewers often note the dramatic mountain scenery, clean water for swimming and the sense of wilderness, while advising careful preparation for weather changes and carrying appropriate gear on longer tracks.
