right the major thing to do in the gerudos training ground is to keep all of your keys until the end, since you only get enough keys to unlock one sequence of doors to the ice arrows.
first go left. Go through the doorway. You
have a limited time to kill two Stalfos'. When they are dead, collect the key. Continue on through the next door.
Welcome to a time limited maze. Collect all five silver rupees using the longshot and the targets to get over the fire barriers. When they are all collected, a door will open up opposite the entrance.
In the next room, as long as you have the silver/golden gauntlets, go straight ahead and push the block into the hole. Then go through the door and open the chest to get a key avoiding the like likes.
Now, go back to the room before (the one with the large block). Pull out your Lens of truth and the Longshot. Look at the opposite wall. There is a hidden entrance here. Hook onto the target to get up there. Go through the door.
In this room, Stand on the circling platform. Pull out your bow. Shoot arrows at the eyes of the statues. if you miss one, you have to start over. When they're all hit, a chest will appear in the middle. After you get the key from the chest, hook up onto one of the targets on the outside and go through the next door.
In the next room, take out the Hammer. Hit the totem polls. The one with three block has a switch underneath it. Press it to make the fire
around the chest in the middle dissappear. Open the chest to get a key.
Now go south, you're in a room with silver rupees (again) and platforms surrounded by lava. Use the Hover boots and float over to the first platform. When Navi runs to a wall and turns green, go to the platform closest to that wall and play the Song of Time to make a time block appear. Jump on it. Now play it again to make another appear. Jump up to the lege above to get a key. Now, jump down and
continue collecting the silver rupees. When the exit door opens, go south through it.
In here, kill the Beamos first. Then take care of the Lizards. When they are all dead within the time limit, you will get another key.
Now, go through the door back to the entrance hall. Go through the door on your right (north). It leads to
a maze. Go to the left side, opening up every door that gets in your way. You should have enough keys. When you get to the end, open the chest to get the Ice Arrows!
