How i can get iron in minecraft?

Mine through stone and you should find some fairly quicky

Go into caves, mine stone, you'll eventually find some.

And this is in the wrong category. Minecraft isn't a sport, less so related to golf.

Go into a cave, I'm sure you'll find PLENTY of resources than.

Or dig a mineshaft i'd say about 3x3, chances are, you'll find a cave that has iron, or the iron itself

Just dig down and side ways you should be able to find iorn in under 5 minutes try digging under water falls
