Sanctuary Mountain is an ancient, vibrant forest protected by a 47km pest-proof fence, the longest of its kind in the world! At 3,400 hectares, it is New Zealand's largest mainland sanctuary and home to many of the country's endangered and at-risk species. Come and experience the New Zealand environment the way it used to be - lush and vibrant with native wildlife including many of New Zealand's rarest plants. Step through the pest-proof fence into another world, where ancient trees tower over well-maintained walking tracks and the air is filled with birdsong. We offer a variety of unique experiences like guided tours and bush walks.
