I added a "related link" that might help you... It's an Ocarina of Time walkthrough that's still being worked on, but is finished with up to right after Dodongo's Cavern! It's on my favorite Zelda site.
You get the bombs from Dodongo's Cavern in Death Mountain.
Go to Dodongo's Cavern on Death Mountain and defeat King Dodongo. Hope i helped!
You have to beat the boss and finish the dungeon. When you come out, a cut scene comes on and Darunia (the god of the Gorons) and he give it to you.
Put a bomb in the center of the room.
throw a bomb flower from the cliff, you do need to get the goron bracelets from darunia in goron city
Dodongo's Cavern is on Death Mountain Trail hidden behind a giant boulder. To remove the boulder you must obtain the Goron Bracelet from the goron leader Darmania. Then use it to grab a Bomb Flower outside the village and throw it down onto the boulder, behind the boulder is the entrance to Dodongo's Cavern.
Ahoy, there. o/ You must come back as an adult, in order to complete it all. You'll also be needing Scarecrow's Song, just as in the Fire Temple
