The village of St Arnaud sits at the edge of Lake Rotoiti in the Nelson region, providing an ideal base for people who plan to hike or fish in Nelson Lakes National Park.Both Lake Rotoroa and Rotoiti are well known for their fine brown trout, and if you walk along the jetty you’ll see some friendly native eels swimming around the waters below. The lakes are a popular destination year round for boating, water skiing, swimming and kayaking, and hosts the annual New Zealand Antique and Classic Boatshow.
