ive been amazed at how many remote islands ive found in the atlantic and pacific. i think the best ive found for surf (at least from what i can see in the pics.) is lle ansterdam. i mean besides samoa and cook islands and hawaii and those obvious ones. if you look at it, check out the pics near the south west coast.
i also really like ascension island, french polynesia, reunion (although its not so remote) and azores
