You did not mention whether you have beaten the Elite 4. However, Mount Ember is small compared to the Seafoam Islands. --FIRST VISIT TO MOUNT EMBER-- First of all, when you defeat Blaine, the leader in Cinnabar Island, Bill takes you directly to One Island's Poke Center. There you will meet with Celio, who is a technician trying to initiate the connection in computers through the islands. At this point you can get out of the Poke Center and head to the shore (right) and go north to Kindle Road. You surf past the Hot Springs (Ember Spa) to get to Mount Ember. At this point, you need surf, strength and rock smash to get to Moltres nest. You get rock smash from a guy inside the spa, talk to everyone there!
