How do you you make travelers tomb appear Pokemon FireRed

You can't truly get Traveler's Tomb on your gameboy, but there is a hacked rom of Pokemon Fire Red, called Fire Red Omega. When you've completed the tasks on all of the other islands, and have made it to Six Island, go to where the Altering Cave will usually be. There you will find Traveler's Tomb, the hardest place in the game, almost as hard as Elite Four,

Traveler's Tomb has many oppurtunities like the Chronum Tower (the very right hand cave door), a long everlasting tower with 1 Hoenn legendary on each floor, as you gradually get higher, the pokemon level will get higher as well, and on the top floor, you will reach a tree and it is a teleporting tree leading you to Celebi.

The middle cave door is Navel Rock, an out of the nowhere island where you catch Lugia and Ho-Oh, no wild pokemon presume here.

And on the very left cave door is the Ancient Labyrinth, you will find some high level pokemon and trainers in here, go through the trainers and the little labyrinth and you will reach Mew.

Other than that, there are two Channelers on a cliff right in front of the Chronum Tower, the left one will automatically heal you pokemon, the left will train you with 6 Lv 99 Blisseys
