This is similar to getting the power bracelet. Take a Fire arrow and shoot it at the Dragon at the top. This will thaw the ice, allowing you five minuets to get in, get out, and get on with life. On the west side of the spiral you can climb up some platforms. Follow the spiral to some ice. Get up and follow the path. Once making it to the top, climb into the hole cave.

Now, shoot all of the Keese with arrows or the boomerang. You can also hit them with your sword. Follow the bridge and fall into the gap. Slide down and find the chest. Open it to get the IRON BOOTS! Now look to the side. Follow the path with the iron boots on. This will protect you from wind. At the bottom are a bunch of ice blocks. Melt them all and kill the enemies. Then hop into the light and get out of here. Head to Gale Isle, which is one space north of Windfall Island.
