There is a pine forest on Sandy Point which is on the south coast of New Zealand near Invercargill - next stop Antarctica! A welter of trails wind their way through the forest like drunken spaghetti - a smorgasbord of intermediate singletrack - ideal for improving beginners and anyone wanting a pleasant spin among the pine trees. There are no hills to cope with - just a bunch of little undulations. It's sandy but the sand is not soft so the riding is as fast as you want to make it. These trails are not exactly packed with features like berms, jumps, and so on but there are lots of curves and little rises and falls - good for gear changing practice.
The trails are all one way and there are little arrows pointing the way and sometimes a trail name. But you could get lost for a while in this forest since all those curves tend to disorient - just keep going till you come to a map board or a sign pointing to the car park. There is a toilet and a small skills area near the car park.
