Adelbert Range Mountains

The Adelbert Range is a rugged mountain range in Madang Province on the north coast of Papua New Guinea. It rises close to the coastal plain and is covered largely by tropical rainforest.

The range supports high levels of biodiversity and a suite of local languages and cultures that are named for the highlands. It is generally remote with limited infrastructure and accessible primarily from coastal Madang Province settlements.

The range sits inland from the Bismarck Sea along the northern edge of mainland Papua New Guinea within Madang Province.

• Biodiversity and languages: Home to a number of endemic species and accounting for several distinct local language groups, making it significant for both naturalists and linguists.
• Access and remoteness: Access is limited and overland travel is remote, typically requiring local guides or river and coastal transport.
