Mount Colro is a mountain peak in the Special Region. The exact location of the peak is unknown. Given the fact that Itami passed it in his journey to the Roldom Canyon in order to hunt the Flame Dragon, it may be located in the northern part of the Tuba Mountains.

The mountain, and presumably the surrounding peaks as well, proved to be an obstruction which forced Itami to take a detour via the Gurban River valley.
