We thoroughly recommend the walk from the camping area to the gun emplacements. These were built at the start of WWII to prevent enemy navies using the outer Sounds as a base for attacks on Wellington and the size of the fortifications and their remote location (in 1939) make their construction amazing. The track has a short steep-ish section at both ends but most of it is level with great views up and down Queen Charlotte Sound. From the camping area to the first gun emplacement is about 40 minutes easy walking.
Beware the wekas! Amazing bird life. Isolated.
