The densely wooded area is located just northeast of Death Mountain, and south of Skull Lake. The area is littered with enemy Forest Octoroks, making it a bit of annoying forest to navigate. However, the forest is a great place for Link to find Zapshrooms, as they are abundant on the floor next to the trees. There are also some rare Energetic Rhino Beetles on some of the trees. With some Big Hearty Truffles and Big Hearty Radishes, this is an excellent place for Link to farm materials.
