Siberia Flat Campsite is a basic DOC campsite located at the eastern end of the Wangapeka Track in Kahurangi National Park, Nelson-Tasman region.

The site adjoins the Rolling River, which flows into the Wangapeka River and is well regarded for fly fishing, though visitors should be prepared for sandflies. The campsite accommodates up to 40 sites and has stream water available.

Access is via an unsealed road on Wangapeka River Road that includes a ford, making it unsuitable for large campervans and potentially impassable after heavy rain.

From here, the Wangapeka Track heads west through the lower valley toward Kings Creek Hut, roughly 11. 4 km away.
