Attack Points
Sometimes, checkpoints are placed in vague areas where everything looks the same. Unless you know exactly where you are, finding a checkpoint in a forest or in a complex area, can be very difficult.
The answer here is to approach the control from a good Attack Point. An Attack Point is an obvious feature, that you can see from a distance, with no similar objects nearby (so you don't get confused). Your Attack Point should be close to the checkpoint - so many orienteers plan their route to the next control backwards...first, identify your attack point and then work out how to get there.
When you reach the Attack Point, take a careful bearing and walk in - many orienteers estimate the distance to the checkpoint and pace count to work out when they're close to the checkpoint.
This page provides some examples of Attack Points and how you can use them to find controls more quickly.
