I would say go north, then follow the arrow to explore south. Maybe those square are few, but we could find something interesting : ressources, goodyhut or a city spot. The land might also continue for a while, so we could explore there. In the worst case, there is nothing and we just have to step back south. we would lose 1 or 2 movment point. That's not so bad if we consider we can find many things there.
