Build Checklist

  1. 01Build and light a portal in Overworld at X=0, Y=64, Z=0
  2. 02Step through, the game will spawn or search for a portal in Nether near X=0, Z=0
  3. 03If no portal was created automatically, build one at X=0, Y=64, Z=0 and light it
  4. 04Travel back to verify the link works in both directions

Java 26.2 note

The game searches for an existing portal within a 128-block radius (Overworld) or 16-block radius (Nether) of the arrival coords. If none found, it creates one at the nearest valid location. Place your portal within that radius of the calculated coords for a guaranteed link.
