What? You didn't think I'd restrict myself to landbased snakes did you? This is a banded sea krait. There are a few species but I believe these are all yellow lipped sea kraits, Laticauda colubrina. It seems to be the most common in the Philippines but I have also seen a black lipped form but I'm not sure which that one was.
check out this old post. Of course like all reptiles sea snakes need air to breathe so any encounter you're lucky enough to have will probably end with a scene like this.
