United States Minor Outlying Islands Travel Guide

The United States Minor Outlying Islands is a collective designation for nine small US-administered territories and atolls scattered across the central Pacific Ocean and one in the Caribbean Sea. The group includes Baker Island, Howland Island, Jarvis Island, Johnston Atoll, Kingman Reef, Midway Atoll, Palmyra Atoll, Wake Island, and Navassa Island (Caribbean). None are permanently inhabited by civilians, and most exist primarily as National Wildlife Refuges administered by the US Fish and Wildlife Service.

These islands are among the most ecologically significant and least-visited places on Earth. Vast stretches of undisturbed coral reef, enormous seabird colonies, nesting sea turtles, and large populations of sharks and pelagic fish define them. Midway Atoll is the most notable exception in terms of visitor access, having hosted one of World War II's pivotal naval battles and now managed as a National Memorial and Wildlife Refuge.

For the vast majority of travelers, these islands are not a conventional tourist destination. Access to most is restricted to scientific researchers, government personnel, and specifically permitted visitors. Palmyra Atoll and Midway Atoll have limited, structured visitor programs. If you are drawn by remote wilderness, wartime history, or serious wildlife research, some islands may be reachable through the appropriate channels — but extensive advance planning is essential.

Permits and Access

Access to virtually all of the US Minor Outlying Islands requires a special-use permit from the US Fish and Wildlife Service (USFWS) or other managing federal agency. Applications must generally be submitted well in advance and are typically granted only for scientific research, educational purposes, or occasionally organized wildlife-viewing expeditions. Do not attempt to visit without proper authorization — landing on a National Wildlife Refuge without a permit is a federal offense.

• Midway Atoll National Wildlife Refuge: Has historically offered limited public visits and volunteer programs. Check with the USFWS Pacific Remote Islands National Wildlife Refuge Complex for current access status, as programs have varied year to year.
• Palmyra Atoll: The Nature Conservancy co-manages the atoll and has facilitated structured research and ecotourism visits. Verify current opportunities directly with the Nature Conservancy and USFWS.
• Wake Island: Administered by the US Air Force; civilian access is strictly limited to authorized government or military purposes.
• Johnston Atoll: Has been closed to public access due to environmental remediation work; verify current status before planning.

Visas and Entry

As US unincorporated territories, these islands fall under US federal jurisdiction. For visa guidance specific to your nationality and destination island, visit TravelerPulse's Visas section and consult the official US Customs and Border Protection website or the relevant managing agency.

What to Bring

There are no stores, hotels, restaurants, or medical facilities on any of these islands. Visitors must be entirely self-sufficient. Bring all food, water, first aid supplies, communications equipment, and any materials needed for your stay. Satellite communication devices are strongly recommended.

There are no scheduled commercial flights or ferry services to any of the US Minor Outlying Islands. Transportation is exclusively via chartered vessel or aircraft, and arrangements are typically coordinated through the permitting agency or an approved research/ecotourism operator.

• Midway Atoll has an airstrip (Henderson Field) and has been accessible by charter flight from Honolulu, Hawaii, when visitor programs are active. Verify current availability with USFWS.
• Palmyra Atoll is reachable by chartered sailing vessel or light aircraft from Honolulu (approximately 1,000 miles south). The Nature Conservancy and affiliated operators have coordinated transport for authorized visitors.
• Wake Island has an operational runway maintained by the US Air Force; civilian access is handled through official channels only.
• All other islands require sea access by charter vessel, with no landing infrastructure. Ocean conditions can be dangerous, and anchorages are often exposed.

The nearest major hub for most Pacific islands in this group is Honolulu, Hawaii. For Navassa Island (Caribbean), the nearest point of departure would be Jamaica or Haiti, though access is highly restricted.

Wildlife and Nature

The primary draw for authorized visitors is extraordinary wildlife. Midway Atoll hosts the world's largest Laysan albatross colony, with hundreds of thousands of birds nesting from November through July. Sea turtles nest on several atolls, and the surrounding waters support large reef shark populations, manta rays, and diverse tropical fish.

• Birdwatching: Midway and Palmyra are internationally recognized birding destinations. Species include Laysan albatross, black-footed albatross, red-footed booby, great frigatebird, and numerous shorebirds.
• Snorkeling and diving: The coral ecosystems around Palmyra, Kingman Reef, and Jarvis Island are among the most pristine on the planet, with exceptional visibility and biomass rarely seen near populated coastlines.
• Historical sites: Midway Atoll was the site of the Battle of Midway (June 1942), a turning point in the Pacific War. Remnants of the battle, memorials, and interpretive programs are part of the Midway Atoll National Memorial. Wake Island also has significant WWII history.

Research and Volunteering

Long-term volunteer positions supporting wildlife monitoring have occasionally been offered at Midway through USFWS. These are competitive and require a commitment of weeks to months. Check the USFWS volunteer portal for current openings.

Health and Medical

There are no medical facilities on any of these islands. Visitors must carry comprehensive first-aid supplies and be prepared for medical evacuation in an emergency, which could take many hours or longer depending on location. Ensure you have comprehensive travel and medical evacuation insurance before any trip.

Communications

There is no cellular coverage on any of the islands. Satellite phones or satellite messenger devices (e.g., SPOT, Garmin inReach) are essential. Internet access, if available at all, is limited to research station equipment.

Weather and Hazards

• Pacific atolls can be affected by tropical storms and typhoons, particularly from June through November.
• Flash flooding, intense sun, and extreme heat are concerns on low-lying atolls with little shade.
• Some atolls, particularly Johnston, have legacy contamination from past military and industrial use; follow all agency guidance strictly.
• Open ocean conditions between islands can be severe; sea crossings require experienced mariners.

Phone Prefix

The US country code (+1) applies, though practical telecommunications require satellite equipment on-island.

Safety on the US Minor Outlying Islands is primarily a matter of environmental and logistical risk rather than crime, as there is no resident civilian population.

• Isolation: Medical emergencies are extremely serious given the remoteness. Evacuation timelines should be factored into all health decisions before travel.
• Marine hazards: Strong currents, reef edges, and large shark populations require caution when snorkeling or diving. Follow guidance from permitted operators at all times.
• Wildlife interaction: Nesting seabirds and sea turtles are protected; maintain required distances and follow all USFWS protocols. Disturbing wildlife or nests can result in federal penalties.
• Environmental contamination: Johnston Atoll in particular has a history of chemical weapons storage and Agent Orange handling. Do not visit without explicit authorization and current safety briefings from the managing agency.
• In any emergency, contact the nearest US Coast Guard sector. Verify relevant emergency contacts through your permitting agency before departure, as operational numbers vary by island group.
