While specific permits for individual natural monuments around Biescas are generally not required for casual visits, it's important to be aware of general regulations. For instance, all Aragonese lakes, including Tramacastilla Lake, are protected as Singular Wetlands, prohibiting activities that could modify water quality, such as bathing with chemicals.
