How do i get through the gates to Lake Hylia on Zelda ocarina of time.?

Answer 1

you can't use the warp until you've been there, so you'll need to ride epona to get in

when she runs straight at a fence, she'll try to jump it. of course, that's something that you probably know anyway, since jumping is required in order to get the horse in the first place

Answer 2

ride Epona directly at the gate and make her go faster and she'll jump the gates
