Wangdue Phodrang is one of the largest dzongkhags in the country. As the district covers 4,308 sq. km and ranges from 800-5800 m in altitude, it has extremely varied climatic conditions ranging from subtropical forests in the south to cool and snowy regions in the north.
Most of Wangdue Phodrang District is environmentally protected. The northern half of the district falls within the Wangchuck Centennial Park, with northwestern pockets belonging to Jigme Dorji National Park. Southeastern Wangdue is part of Jigme Singye Wangchuck National Park. Also protected are the biological corridors crisscrossing the district that connect Bhutan's extensive national park system.
