This magnificent 70-hectare (173-acre) woodland park is a testament to one man’s passion for trees. It’s also a beautiful place to while away the rest of your day. The work of William Douglas Cook, who began planting the bare site in 1910, is the loveliest and largest arboretum in New Zealand, boasting more than 3,500 species of trees. It’s a haven for scientists, photographers, garden enthusiasts, and picnickers. There are over 25km (16 miles) of walking tracks and plenty to see; guided tours are available at additional cost. Plan a picnic under the maples.
