If you don't mind mud, that's the way to go. We've found quite a bit on Koru already. Nice and muddy down there. But the idea is to cover the worst with gravel. Most areas are rideable in the wet.
Some trails are tight and in bush, other more open and faster.
There's even a water hazard. In short, there's a little bit of something for everyone. There are so many mountain bikers in Wellington that there's pressure on the Council to provide services for them. And with Makara Peak, provide they have.
