Uta Lower Road

Uta Lower Road is a path that goes underneath a river and across some mountains heading left that takes you from the Wicked Ditch to the Debious Woods. To reach it from the Wicked Ditch, when you encounter an "impassable" river, you need to use the Red Crystal in that same manner that the Blue Crystal was used at Yuba Lake, that is, kneel down at the bank. A path beneath the water will be revealed and you can take it. Once you cross the river, you will be at a mountainous area. The Flame Whip can be found here. You can head straight upward the mountains or to the left to the Debious Woods.
