The clue book in the Library gives you a set of course headings and distances to a series of locations, which turn out to be holes in the ground.
Once you can work out how to measure distance using the numbered flags around the cage at the link in point, following the directions, if done carefully, will lead you to the holes. But this is very difficult to do, especially on the later holes, which have many changes of direction. Small errors build up, and you can end up quite a long way off.
Best bet, seems to be to draw out the courses and plot a direct line from the cage to each hole, and try to go straight there in one move.
Hole 4 is the longest run in Minkata and twists over a huge area of the age. Part of the difficulty here is that visibility is beginning to deteriorate when you get near the hole, so you have to be that bit closer to see it. In golfing terms, this hole is "Stroke Index 1".
Here's another way to tackle this one:
Walk from the cage toward the left of the pair of green flags (towards the West). Stop when you're about 10-15 metres from the flag and turn South:
Line yourself so the shortest shadow is just left of centre behind you. Now RUN for 95-100 seconds (no more than 100). The hole should be nearby.
On top of the cage, stand in the center of the compass rose and face South. Turn two pips on the compass clockwise, then RUN in that direction for 112-115 seconds. Then look around you.
A few seconds out from the cage, you should begin to see a large bone lying on the ground ahead of you: If necessary, adjust your direction so that you pass right over this bone. Try to do this as early as possible - a last minute "jerk" will just take you further off-course rather than helping.
