Select the course "Ruins". Then find the jetpack. After you find the jetpack fly over to the road that makes a small circle in the the left side of the map. There you will find a temple. You can use the jetpack to fly in the top OR go to the back of the temple where there is a small entrance.

On the GRAVEYARD level when you are about to go through the 4th checkpoint, turn to you're left and go over the hill (be sure to go through the checkpoint).
