MIDWAY ATOLL – The long stretch of atolls and coral reefs northwest of the main Hawaiian islands is so precious humans generally aren’t allowed to venture there.

Boats need special permits to enter. All fishing must stop in 2011, aside from what Native Hawaiians catch for cultural purposes. President Bush made the region the largest protected marine area in the world when he declared the Northwestern Hawaiian Islands a marine national monument last year.

But there is one spot in the 1,400-mile archipelago where officials believe human visitors, in limited numbers, could do more good than harm: Midway Atoll.

In about six months, the U.S. Fish and Wildlife Service plans to allow tourists to visit Midway, primarily to help clear the island of debris and invasive species. Wildlife officials also hope visitors will leave having become strong advocates for the continued preservation of the monument.

“That is such a treasure that America is not yet aware of,” Interior Secretary Dirk Kempthorne said during a recent visit to the remote island. The monument, recently named Papahanaumokuakea, is home to thousands of species found nowhere else in the world. Kempthorne said it was America’s equivalent of the Galapagos Islands and the Great Barrier Reef.

Midway, in the upper extreme of the island chain, is a three-to-five-hour plane ride from the nearest city, Honolulu.

The Navy used the island as a base for decades during the Cold War but left in 1996.

Now refuge workers need help clearing harmful marine debris – such as fishing nets and hooks – that entangle and kill honu, fish, and monk seals.

Authorities plan to allow the first tourists sometime between November and January, most likely in groups of 15 on a chartered plane from Honolulu. No more than 40 overnight visitors would be allowed.

A weeklong stay would cost one person about $3,600, including airfare from Honolulu and lodging in old military barracks.

Vacationers beware: Don’t expect to treat the atoll as the new Waikiki or Maui. Midway is no resort.

Tourists won’t be able to go water skiing or kite-surfing, although authorities will allow less disruptive activities including swimming and snorkeling. There’s no shopping aside from a small gift store.

“Those that will ultimately come will want to pitch in,” Kempthorne said.
