I have just become adult Link.I am supposed to go to the forest temple..

What you need is the hookshot so you can grapple onto the tree above the peice of broken bridge. Go to Kakarikio Village and go to the graveyard at the back of the village. If you go behind some of the tomb stones you can pull them back. A certain one will contain a hole and if you drop down you will see a creepy looking guy just floating in the air. Go talk to him and tell him you want to do his challenge. All you have to do is follow him but move quickly and at the end he will give you his "treasure" which is the hookshot. Good luck!!!

Way to go zeldafanatic5493 =D

First, you need to go to the Graveyard behind Kakariko Village to get a new weapon that'll help you get into the Forest Temple. There's a new tomb there now, it's first one on the left-hand side - enter it. Dampe'll challenge you to a race, it's pretty hard so you'll need to do it a few times until you know which way to go. Once you beat him, you'll get the Hookshot - now play the Minuet of Forest to get to the Sacred Meadow where Saria used to be and use your new weapon to enter the Forest Temple!
