This achievement is a simple one to obtain, and you’ll likely do it within the first few days of your campaign. A hideout is classified as any place where bandits have gathered in sufficient numbers to call it one. There are many hideouts throughout Calradia, and you’ll often find them around mountain passes which are strategically located close to nearby towns and villages. An example of a hideout is shown in the screenshot below. All you need to do to clear one is enter and kill all of the enemies present, including the leader at the end.
