The End Portal is a structure in the game Minecraft that allows players to access the End, a dimension where the Ender Dragon resides. To activate the portal, players must place End Portal Frames in a specific arrangement and insert Eyes of Ender into each frame. Once activated, the portal creates a shimmering surface that players can jump into. The End Portal is typically found in Strongholds, which are underground structures scattered throughout the game world. Players can locate Strongholds using Eyes of Ender, which lead them to the nearest one. Once inside a Stronghold, players can find the End Portal room containing the portal itself.
