This will ignite the portal and create your pathway to the Nether. The final step is to take a flint and steel, which can be made by crafting together flint and a bar of iron, and right-click on one of the two bottom blocks.

If you’ve done this correctly, there should be a two-block wide and three-block tall opening with edges made out of obsidian.

The smallest shape of a portal is as follows, two blocks of obsidian on the bottom with a filler block of some kind in the corners, three blocks of obsidian on top of each of the two fillers, and then two more blocks of obsidian across the top. At least ten blocks of obsidian are needed to make a portal so gather those up and head over to wherever you want to build it. A diamond pickaxe is needed in order to mine this block, and even then it will take a while. Obsidian is created when water flows over lava source blocks, and as such can sometimes even accidentally form deeper underground due to stray water flow. The primary block that’s needed in order to make a Nether Portal is obsidian.

The exact size and shape of a Nether Portal can come in many different forms, so we’ll mainly be looking at what’s needed to make a basic portal. The Nether is one of the most expansive and interesting parts of Minecraft, so we’ll be taking a look at how to make a Nether Portal.
