Ice Cavern

Once at Zora's Domain, you'll notice everything is frozen. Head to Zora's Fountain and jump from iceberg to iceberg to get to the Ice Cavern on the far side. Once in, head down the path until you come to a big opening. Destroy all the enemies and the next door will open. Soon you'll come to a room with 2 big spinning ice blades. Collect all the Silver Rupees to continue through the door on the top right. You'll soon be in a room with Ice Bats. Collect the blue flame in a bottle. (as many as you can. Fill the bottles whenever you come across them in this area.) Now use the flame to melt the ice covering up objects. Get the map in the back and head back to the ice blade room. Melt the ice wall on the right side of the map and you'll find the compass. Now go through the ice wall on the other side of the blade room and slide the block on the ice to collect the silver rupees. If you get it in a spot you can't recover from, push it off the edge and it will come back at the beginning again. Enter the door and you'll soon come to a room with a White Wolfos. Get the Iron Boots and learn Serenade of Water from Sheik. Now go back to Zora's Domain and melt the ice covering King Zora. He will give you Zora's Tunic. Now head to Lake Hylia.
