Atene Skyline Campsite is a backcountry site positioned at the halfway point of the Atene Skyline Track in Whanganui National Park, Manawatū-Whanganui. Managed by the Department of Conservation, the campsite sits in a clearing at approximately 260 metres elevation along the ridgeline, accessible via a track that climbs steeply through lowland forest from Whanganui River Road. Facilities include drinking water, a shelter and a toilet. The site operates on a first-come, first-served basis with no bookings required, catering to trampers tackling the track known for its spectacular views over the surrounding national park landscape.
