Overview
Palmyra Atoll is one of the most remote and ecologically pristine places under United States jurisdiction, situated roughly 1,000 miles south of Honolulu in the central Pacific Ocean. It is an unincorporated territory of the United States and is not part of any U.S. state. The atoll encompasses about 50 small islets surrounding three lagoons, with a total land area of less than 5 square kilometers.
The atoll is jointly managed by the U.S. Fish & Wildlife Service, which administers the Palmyra Atoll National Wildlife Refuge, and The Nature Conservancy, which owns much of the private land. Together they have made Palmyra a field station for scientific research focused on coral reef ecology, climate change, and marine biology.
Unlike most U.S. territories, Palmyra has no permanent civilian population. The only people present at any given time are researchers, refuge staff, and conservation volunteers operating through formal programs. This makes Palmyra fundamentally different from any conventional tourist destination — it is a living laboratory rather than a travel market.
Before You Go
Access Is Highly Restricted
Palmyra Atoll is not open to general tourism. Entry requires a permit from the U.S. Fish & Wildlife Service, and in practice visits are limited to researchers, authorized scientists, conservation program participants, and occasional permitted recreational users (primarily sport fishers and divers) under very controlled conditions. Independent travel is not possible.
Visas and Entry
Because Palmyra is U.S. territory, U.S. citizens do not require a visa to enter. Non-U.S. citizens should consult TravelerPulse's Visas section and verify current U.S. entry requirements through the official U.S. Customs and Border Protection website, as standard U.S. immigration rules apply in addition to the special refuge permit requirement.
What to Prepare
- All supplies — food, water, fuel, medical equipment — must be brought with you. There are no shops, restaurants, or medical facilities on the atoll.
- Satellite communication is the only reliable means of contact with the outside world.
- Participants in formal research or conservation programs will receive detailed logistics briefings from their organizing institution before departure.
- Travel and emergency evacuation insurance is strongly recommended given the extreme remoteness.
Getting There
By Charter Aircraft
The primary means of access is via charter flight from Honolulu, Hawaii, to a paved airstrip on the atoll originally constructed during World War II. These flights are not commercially scheduled; they are arranged exclusively through the U.S. Fish & Wildlife Service or The Nature Conservancy for authorized visitors.
By Private Vessel
Some permitted recreational users arrive by private yacht or charter vessel. A permit from the U.S. Fish & Wildlife Service is required well in advance. The passage from Hawaii is roughly 1,000 nautical miles and demands an experienced offshore crew and a well-provisioned vessel capable of open-ocean sailing.
There are no commercial ferry, cruise, or passenger shipping services to Palmyra. Anyone planning a research affiliation or conservation volunteer stay should coordinate all logistics through the authorizing institution, as they manage transportation arrangements.
Things to See & Do
Marine Research and Observation
Palmyra is one of the healthiest coral reef systems remaining in the Pacific. For those who gain authorized access, scientific diving, fish population surveys, and coral monitoring represent the core activities. The atoll is a reference site for understanding undisturbed reef ecology.
Seabird and Wildlife Observation
The islets host large colonies of seabirds including red-footed boobies, frigatebirds, and white terns. Sea turtles nest on the beaches, and the surrounding waters support large populations of sharks, manta rays, and a wide variety of reef fish. All wildlife is strictly protected under the National Wildlife Refuge system.
Sport Fishing (Permitted)
Limited permitted sport fishing access is occasionally available for recreational anglers seeking giant trevally and other pelagic species in one of the least-pressured fishing environments in the Pacific. Verify current permit availability and conditions directly with the U.S. Fish & Wildlife Service.
Historical Exploration
Palmyra has a notable World War II history, and remnants of wartime infrastructure — including the airstrip, concrete structures, and naval equipment — remain visible on the islets. The atoll was also the site of the infamous 1974 Mac and Muff Graham murder case, which is a documented part of its history.
Practical Information
Communications
There is no cellular network on Palmyra. Satellite phones and satellite internet connections used by the research station are the only means of communication. Visitors should not expect personal internet access unless it is provided as part of a formal program.
Health and Medical
There are no medical facilities on the atoll. Visitors should arrive in good health, carry any personal medications in sufficient supply for their entire stay plus contingency days, and hold comprehensive travel and emergency medical evacuation insurance. The nearest hospital care is in Honolulu.
Power and Infrastructure
The research station has generator-supplied electricity. Visitors staying as part of a research or conservation program should clarify what charging facilities and infrastructure are available through their host organization.
Emergency Contacts
In a genuine emergency, contact is made via satellite communication to the U.S. Coast Guard or coordinating agencies. Confirm emergency protocols with your organizing institution before departure — do not rely on local emergency services that do not exist on the atoll.
Safety
Palmyra Atoll is an extremely remote environment with no emergency response infrastructure on-site. The greatest risks are medical emergencies requiring evacuation, ocean and weather hazards during transit, and diving-related incidents far from hyperbaric care.
The surrounding lagoons and ocean waters contain significant shark populations; diving protocols for the atoll are established by the research station and should be followed strictly. Tropical weather, including occasional cyclonic activity, can affect the region, particularly during the November–April and April–November transition seasons.
All authorized visitors should carry personal locator beacons (PLBs), ensure their organizing institution holds their emergency contact information, and familiarize themselves with evacuation plans before arriving. The U.S. Coast Guard provides search and rescue coverage for the region, but response times from this distance are substantial.
