The reserve covers the upper part of the Kahika Stream.
Together with the bush-clad lower reach of the stream, which passes through private land, the bush in this reserve forms a significant wildlife link.
The open paths lead through native bush and provide community connections to local schools, besides a forest stream experience for visitors. All the main paths have steps, with footbridges over the stream.
An old group of kauri is closed off to protect them, but other paths pose little danger to kauri, so are free to enjoy. The reserve has been invaded by wattles, pines and garden escapees in the past, but much original bush remains and is being restored for the future.
There is plenty of food for birds and a wide range of forest birds can be seen and heard here.
Part of the bush is within the grounds of Birkenhead College and students are working to restore that area.
