You capture Moltres and the summit on Ember Island, situated on Knot Islands. Moltres will be level 50. We recommend you save before battling Moltres, just in case you lose, because Moltres will then fly away. Make sure you pack heaps of pokeballs, greatballs or ultraballs. *This answer has been approved and written by Wikia Lord.
You can capture Moltres at Mt. Ember Peak and Zapdos in the Power Plant in FireRed.
Moltres cannot be found in the Desert Resort due to not being available for capture in Pokémon Black. You would have to either trade for a Moltres or transfer one from a previous game using the Poké Transfer Lab in Route 15 in order to receive a Moltres within Pokémon Black.
if you see the light blue water, go down to the grass.
