Wales' official take on wild camping is that you must ask for landowner permission first. In practice, finding the landowner to ask can be tough. If you do camp, stay on moorland and out of cultivated land. Many areas, including Elan Valley Lakes, strictly prohibit wild camping. Shelter in the moorland around Rhayader is scant—come prepared with full, wet-weather gear. You can also explore different options for camping near Rhayader on Hipcamp.
