Pokémon FireRed and LeafGreen/Mt. Ember

'Finally, you have found the home of that Pokemon that has eluded you for so long. At the end of this road, Moltres awaits your arrival. Luckly, the path is short and sweet. Crush your opposition and reach the top of Mt. Ember!'

Entrance
At last you've arrived to Mt. Ember. Before confronting the mountain, make sure to bring plenty of Ultra Balls and Burn Heals. In addition, an Escape Rope or two would not be also a bad idea.

The first person you'll meet is in fact a Move Tutor, who will offer to teach one of your Pokemon. If you head East from the entrance, you will see two Rockets planning something. They are obviously up to no good, but it is not yet time to interfere with their plans.

Take the West path of the mountain. You will need to use to continue and tackle the trainers. When you reach a rock that can be broken with, do so, and enter the cave hole. Following the other path will only lead you to a dead end.

Within Mt. Ember
The trip within the caverns of Mt. Ember is somewhat long, but impossible to get lost in. Just head north to escape the confines of the mountain. Consider making use of some Repels just so you can avoid the great numbers of s you'll encounter on your way up.

Mt. Ember Summit


Finally, Moltres is on sight. Solve the very easy puzzle using a Pokemon with Strength. If you mess up, just go back in and out of the cavern. Once past it, save before confronting Moltres. It will be an arduous battle, but eventually, the Legendary Bird will be yours!

Finally, now that your business is over, you might want to make use of that Escape Rope. Just remember to pick the items from Mt. Ember before you do!

Head to One Island and board the ferry. It is time to meet your final Gym challenge at Viridian Gym!
