There truly is only one way into the crystal cave, but I can explain it easily. You use the map to go to
Starting Point 6, which is marked with a marine bike. Use an ATV. When you get there, turn right. You see a ramp with a gap. Drive over the ramp and go into the cave thingy. Drive through the cave thingy until you see a bridge. Turn right onto the bridge and get to the other side. Then turn left onto a hill marked with black torches, and go up the hill. Now you will see a path with rocks in between. Go down the path on whatever side you please until you see a cabin with a man on the front porch. This is also where the path separates into two. Go to the cabin and stop in front of it. Turn around to face the rocky wall. Look carefully, and you will see two people in racing suits on top of the wall! In between them is a large gap. Nearby the wall is a ramp. This will take a few tries, but use the ramp to get through the gap. Now you'll be falling down a rocky hill and you can't brake until you reach the bottom. You'll be in a grassy place with a few plants. Keep going downhill in whatever place that goes downhill and then you'll be falling, falling, falling until you reach... the crystal cave!! The treasure chest is easy to find-- just keep going deeper into the cave until you see it on the top of a bunch of stone platforms. When you find it, you'll get a ninja suit that you can wear in the Villa Grounds!
