Papahānaumokuākea

Northwest of the main Hawaiian islands the chain continues for nearly two thousand kilometres as low atolls, reefs and single rocks, and the marine area around them is one of the largest protected places on earth, larger than all the national parks of the mainland combined. It carries a rare mixed World Heritage listing, recognised for nature and for culture together: Nihoa and Mokumanamana hold ceremonial sites and the region is central to Native Hawaiian accounts of ancestry, its name referring to the union of the earth mother and sky father. The wildlife is extraordinary, with about three-quarters of all Hawaiian monk seals, millions of nesting seabirds and green turtles. General visits are not permitted, which is the point of it.

What you actually see

• The listing itself - a rare mixed site, valued for nature and culture together.
• The wildlife - monk seals, green turtles and millions of nesting seabirds.
• Nihoa and Mokumanamana - ancient ceremonial sites on remote rock islands.
• Bishop Museum, Honolulu - where the region can actually be seen and understood.

When to go

There is no visitor season, because there is no general access. The realistic way to engage with it is on Oahu, at the Bishop Museum and the monument's education programmes, or through the documentary and research material published about the reserve.

Honest expectations

This is on the list because it matters, not because you can go. Permits are issued for research, resource management and Native Hawaiian cultural practice, and tourism is not among the permitted uses; occasional limited access to Midway Atoll has been offered in the past and has been suspended for years. Treat any operator selling trips here with deep suspicion.

Nearby

Honolulu and the Bishop Museum are the practical starting point.
