If your playing game cube you go to the western gate or the Wii you go to the eastern gate and there is the pathway to the lake you go to the bridge and the monster sets it on fire and there's boxes to push and you jump on them to jump off the bridge if you didn't pass that part already.
If you passed that part then as a wolf you can warp there, and as a human you go to the mini game by the bridge, which cost 20 rubes, you get a chicken and jump off. (usually you can just forget it and just jump in the water)
Well there are series of events you have to go through like you have to have all of the mirror shards and you have to have killed zant then you can go to hyrule castles for your final boss
In twilight Princess
in the beginning of the game there is only one entrance from left or right(depending on your system) since the opposite bridge is destroyed and a rockslide covered the south entrance (no north road, hyrule castle is in the way=( )
but in kakariko you can donate 1000 rupees to fix the bridge
and you can do the extra mission of bringing hot water to the lazy goron on the new bridge as he will get hot spring water to sell for you in castle town as you can bring some to the goron in the south field of castle town so he can clear the road
In OoT
hyrulecastle is always open except in childhood at night
in the north of hyrule field
There are two ways you can do this.
1. Go to Gerudo Valley and jump down into the gorge. Follow the current down stream and you'll find yourself at the lake.
2. Go to the intersection where you can either go to Gerudo Valley or keep going in hyrule field.
Do not enter the valley just keep going. You will soon see some towers and gates to your right. there should be a wall extending from the rightmost tower closest to you. follow that wall until it ends. there will be a ladder that you can use to bypass the towers into the lake area.
It took me a while to figure this out too. !
Lake Hylia lern the serinade of water and play it you will appear in lake Hylia

lake hylia
The Waterfall of Wishing is at the Northeast corner of Lake Hylia, Between the Witches Hut and Zoras River.
There are four feet from the Great bridge Hylia to the lake in Twilight Princes. This is made into a game.
Get the silver scale in Zora's Domain, then go to Lake Hylia through the warp door. The letter is near the door at the Lake Hylia end.
warp
You have to go to the bottom of lake Hylia.
After you beat the Water Temple, then the lake fills up due to the rain. But first you need the Hookshot, metal boots, and the bow. The hammer helps as well.
you get it in the temple at the bottom of lake hylia
Do the Zora diving game. Win it. The you will get the Silver Scale that allows you to dive deeper. It allows you to dive for 6 seconds. That will allow you enough time to dove to the bottom of Lake Hylia to get the bottle.
Use Minda to warp the giant lava rock from Death Mountain to the frozen part of the lake.
