Alternatives

In the child section, taking the owl at lake hylia to hyrule castle is almost as fast as going down Zora's River after giving the letter to king zora. If you decide to take the owl, don't plant the bean until your return trip to lake hylia after giving the letter to king zora.

On N64, you will not be able to use deku sticks as adult or the game will freeze.

If you can't do the gerudo bridge megaflip, you should steal epona from Lon Lon ranch and use her to jump the bridge.

If you are on N64 and can't do the no ISG gerudo bridge megaflip, you will need to equip sword to get ISG for stealing epona or ISG megaflip, then go back to lake hylia and steal the rod OR get hookshot when getting bombs from graveyard and hookshot across.

If you are not good at hovering or are low on bombs at Ganon's Castle and don't want to rely on luck from beamos, you can always do the classic armos in spirit trial method for trial skip, however it is 30 seconds slower.
