Kalawao County, Hawaii

Kalawao County is a county located in the U.S. state of Hawaii. The county encompasses the Kalaupapa or Makanalua Peninsula, on the north coast of the island of Molokaʻi. The small peninsula is isolated from the rest of Molokaʻi by sea cliffs over a quarter-mile high—the only land access is a mule trail. According to a 2016 census estimate, Kalawao County was the least-populated county in the United States and occupies the least area of any county.

Because of the small population, Kalawao County does not have the functions of other Hawaii counties. Instead, it is a judicial district of Maui County, which includes the rest of the island of Molokaʻi. The county has no elected government.

It was developed and used from 1866 to 1969 for settlements for treatment of quarantined persons with Hansen's disease (leprosy).

History
The Kingdom of Hawaiʻi, the Republic of Hawaiʻi, the territory, and the state of Hawaii exiled persons suffering from Hansen's disease to the peninsula, from 1866 to 1969. The quarantine policy was lifted after effective antibiotic treatments were developed that could be administered on an outpatient basis and patients could be rendered non-contagious.

Many of the residents chose to remain on the peninsula, as they believed their disfigurements from the illness would make reintegration into society impossible. The state promised that they could live there for the rest of their lives. No new patients, or other permanent residents, were later admitted. Visitors are permitted only as part of official tours. State law prohibits anyone under the age of 16 from visiting or living there, although exceptions have been made for children visiting their relatives.

The Kalaupapa National Historical Park was established to preserve the county's history and environment. It is coterminous with the boundaries of Kalawao County.

Geography
Kalawao County is included in the Kahului-Wailuku-Lahaina, HI Metropolitan Statistical Area.

By land area, it is the smallest true county in the United States, although Falls Church, Virginia is smaller but is an independent city with county-level governance and is not a county or part of one.

Kalaupapa Peninsula
Kalaupapa Peninsula contains the county's only settlement, Kalaupapa. The Kalaupapa Peninsula developed from lava that erupted from the ocean floor near Kauhako Crater and spread outward, forming a low shield volcano. This was the most recent volcanic episode on the island and of the larger East Molokaʻi shield volcano, occurring after the formation of the cliffs by erosion.
