It's difficult to tell what you mean, but I'll assume you mean the pyramid. First, go straight down, jumping off the ledges until you reach the ground. Then travel one screen right, one screen down, one screen right, then continue right until you find the group of orange trees. Go up from here, you'll see an arrow pointing upwards to a thick light green bush. This bush is a small maze which is quite easy to navigate - (Up, left, up). Go up and follow the bushy border around the building you'll find. Ignore the gap in the bushes above you and continue left through the gap you'll find further on. Head up until you find a gap to your right and go through it toward the large, thick bush. After this, head immediately down. You'll find a gap in the large bush leading right inside the bush. This is another maze which is more complex and difficult to describe. Just follow the brown pawprint-looking marks that you can see on top of the bush, remaining in the lower half of the bush. It's simpler than it sounds. When you emerge on the other side, there will be a purple monkey following you. He'll ask for ten rupees, which you should give him. Head right through another gap, up through another,then head right until you see the palace. Go up to the entrance and the monkey will ask for 100 rupees to open the door. Give them to him.
