To go to the Nether, you need to build a obsidian gate Then light it with a lighter. You don't need to explore the real world to find it—you can build it yourself in just a few minutes.
This guide shows you how to do it step by step Minecraft.
We'll also take a look at the unique features of this dimension, the creatures that live there, and the items you'll need to collect to survive as you explore the Nether.
I. How do I get to the Nether?
In Minecraft, there are 3 different sizes:
- The surface, the normal world where you start your game, also known as Overworld.
- The Nether, also known as the Depths or Hell, the dimension we are discussing here.
- L'End, the world of the dragon, also known as Ender. Discover How to Get to the End if you want to go there after the Nether.
To access these last two dimensions, you'll need a specific portal. In the case of the Nether, this portal must be built by hand. To do this, you'll need at least:
- 10 obsidian blocks
(sorted by 64, Creative tab in the bricks, ID = obsidian). You'll need a diamond pickaxe to mine this block.
- 1 lighter
(does not stack, "Creative" tab in Tools, ID = flint_and_steel).
To get obsidian without a pickaxe at the start, pour water on lava: when the two come into contact, they create a block, which you can then break with your diamond pickaxe. This is the fastest way to get obsidian without having to search for it in the normal world.
Building the Nether Portal Step by Step
To build the portal, arrange the blocks in a 4×5 frame. You can also build a 2×3 frame if you use only the inner part—that is, without the four corners. Once the frame is complete, use the lighter to light the top of one of the blocks outlined in red.
The least expensive portal is the one with the corners removed, on the left: you'll need 10 obsidian blocks, compared to 14 for the portal on the right with the corners. To use less obsidian, simply leave the four corner slots empty; the portal will still work.
How to Light the Nether Portal Without a Lighter
If you don't have a lighter, you can still activate the portal. A Ghast's fireball that hits the frame will set it on fire. These solutions save you from having to craft a lighter in a hurry.
Once the portal is lit, stand inside the frame and wait a few seconds. A loading screen will appear, and then you'll find yourself in the Nether.
Building the portal is the key step in gaining access to the Depths.
