Us The Legend of Zelda: Echoes of Wisdom guide will show you the full walkthrough of Still Suthorn Forest.
Walk through the silent Suthorn forest
Start Stilled Suthorn Forest by jumping over the first two floating islands. On the third island, call a spear moblin to attack the blob enemy from a distance before moving on.
After the blob is defeated, go right. Jump over the floating trees and enter the cave at the top of the next floating rock.
Call in the cave a spear moblin to deal with the keese. Then cross the gap and place a pot (or another weighted object) on the switch that the arrow is pointing to in the screenshot below. That will open the gate at the top of the room, allowing you to proceed.
In the next room, summon enemies to deal with the blobs. There are five of them, so you may need to summon two enemies. (A ignazol followed by a rope (worked wonders for us.) The door at the top of the room will open once all enemies are defeated.
Once you get back outside, you’ll find yourself on a floating island with paths leading to the bottom left, top left, and top right.
