What is the best y level for iron in 1.20 bedrock?

For optimal iron mining in Bedrock Edition 1.20, the best Y level is generally considered to be Y=16.

• Why Y=16?: This level strikes a good balance between the increased iron generation below Y=0 and the lava level, minimizing encounters with lava pools that can hinder mining. It's also high enough that you're unlikely to hit bedrock while creating large mining spaces.

• Iron Ore Generation: Iron ore generation is affected by world generation mechanics and peaks at Y=16. However, note that the largest amount of iron is found between -16 and 80.

• Lava Pools: Lava pools become more frequent as you go lower, which makes Y=16 a nice middle-ground to avoid them.

• Mining Techniques: Effective mining techniques like branch mining can improve your iron yield at this level.

Remember that ore generation can still vary slightly due to the random nature of world generation, so exploring around Y=16 can still be beneficial.
