South of Loho, there is a very small strip of sand. To the south of that is a small green piece of land with a mountain range on one side and some cliffs on the other. When your boat gains wings, fly onto the sand, and position your boat so that it faces the green strip of land. Now press A to attempt to jump out of your boat. If your positioning is correct, you'll jump across the green strip and into the world of Golden Sun 1. Most bridges are still there, but there are no caves, nor can you enter Vale.
