In Seafoam Islands, (across Cinnabar Island), You will have to battle trainers to reach the ladder on your right once you get to the last trainer. Then, ignore the two ice patches you see and head down the ladder. Surf around the right corner until you reach the island where Articuno was. Note: the island I was talking about was the low island in the bottom of the upper island. Get ready to fight Articuno!
