Mount Wilhelm National Park protects the highest peak in Papua New Guinea, offering challenging hikes, rich biodiversity, and dramatic mountain vistas.
Mount Wilhelm National Park is located in the central highlands of Papua New Guinea and encompasses the region surrounding Mount Wilhelm, the highest mountain in the country at 4,509 meters (14,793 feet). The park features a diverse landscape with alpine grasslands near the summit, dense montane forests on the slopes, and tropical rainforest at lower elevations. This variety creates unique habitats supporting a wide range of plant and animal species, including many endemic birds and rare orchids. The park's terrain is rugged and steep, attracting experienced hikers aiming to summit Mount Wilhelm via trails that start from nearby villages such as Keglsugl. The climb is often done over two to three days, with basic campsites and small villages providing stops along the way. While less developed than many national parks, its remote location adds to the sense of adventure. The area also holds cultural significance for local indigenous communities who live in the park's buffer zones and often guide climbing expeditions. Visitors are drawn to the challenging mountain trek, opportunities for birdwatching, and the chance to experience traditional Papua New Guinea highland culture. The park plays an important role in conserving the fragile ecosystems of the highlands and maintaining water sources critical to downstream communities. Mount Wilhelm itself serves as an iconic landmark and a focal point for ecotourism and outdoor activities in the region.
