Whakapapa Scenic Reserve is a walking track at Ōwhango in Ruapehu, with a Google rating of 4.8 from 37 reviews.
A good walking track is one you can read before you set out, so check the current conditions and allow more time than you think you need. On mountain and bush tracks in the central North Island, weather can turn quickly, so sturdy footwear, a warm layer, water and a rain jacket are worth carrying. It helps to tell someone your plan and your expected return time, especially if you are walking alone. Regulars tend to start early, when tracks are quieter and the light is good for photographs.
For a walk near Ōwhango, plan around the weather and leave time to enjoy the reserve at an easy pace.
