Four island states, one extraordinary Pacific: manta channels, WWII wrecks, living reefs and rainforest heritage
Use this travel brief to set arrival flow, local transit, and gear movement before you lock your itinerary.
Fly to one of four state airports: Yap (YAP), Chuuk on Weno (TKK), Pohnpei (PNI) or Kosrae (KSA). FSM tourism describes United Airlines routes via Guam and, for the eastern island-hopper services, Hawaii; Yap can also be linked through Palau. Frequencies and stop patterns change, so verify the ticketed route directly with the carrier. The islands are geographically far apart; inter-state flying can require multi-stop routing and schedule buffers. Outer-atoll voyages or rare air services require direct local arrangements, often months in advance. An overnight transit through Guam, Hawaii or Palau can create additional entry/document obligations.

Airport serving Kolonia, Nett and Pohnpei and Nearby Atoll Excursions.
Transport: Hotel or dive-operator pickup, Local taxi, Rental car
Taxis and limited car rentals exist in the state centers; there is no broad city-style public transit network or app-based ridesharing. Reserve airport transfer, dive boats and land excursions through a hotel or licensed local operator. Main island roads vary in surface quality, lighting and vehicle conditions. Outer atolls are reached only through specialist arrangements; inter-state travel is normally by air, not an ordinary island ferry. Respect private and customary land ownership when approaching beaches, ruin sites or reef entry points.
FSM's official tourism guidance states that most visitors require a valid passport, sufficient funds and proof of onward travel, and that ordinary visits of 30 days or less do not require an advance entry permit. Longer stays generally require immigration authorization; U.S. citizens have special Compact of Free Association provisions, so confirm the applicable rule directly with FSM immigration rather than relying on the ordinary 30-day language. FSM tourism says passports should be valid at least 120 days beyond entry; U.S. State Department guidance for U.S. travelers instead specifies six months. Use the stricter six-month buffer when possible. Expect an arrival CIQ form and immigration/customs checks between states. Transit through Guam, Hawaii or Palau may require separate clearance. Rules are subject to change.
Standard scuba tanks and weights may be supplied by local dive operators, but sizes, valve fittings, nitrox, rental quality and spare parts vary by state. Chuuk's dedicated wreck operations may offer specialist gases or rebreather support only by explicit advance agreement. Bring computer, prescription mask, serviceable personal essentials, suitable exposure protection, signaling equipment and proof of certification. Ask the airline about baggage limits and whether the liveaboard permits your planned technical equipment. For freediving, confirm a named qualified safety supervisor; do not infer a depth line or rescue team from a scuba operator's listings.
United States dollar (USD)
USD is the official currency. Hotels, some operators and larger restaurants in state centers may accept major cards, but cash is essential for smaller shops, village fees, taxis and departure taxes. Remote islands and boats may have no electronic payment option.
Banks and ATMs are concentrated on the main islands, not outer atolls; official Australian guidance warns that most airports lack ATMs. Withdraw and carry enough small USD notes before remote outings.
110-120V • 60Hz • A, B
U.S.-style flat-pin outlets are standard; national tourism describes 110V while other travel references say 120V. Check a vessel's actual supply, power stability and adapter requirements before charging cameras or dive lights.
Communications
FSM Telecommunications Corporation advertises cellular and internet services in all four states, with prepaid options. Actual speed and coverage are uneven, especially offshore, on outer atolls and in steep valleys. Download offline maps, boarding documents, emergency numbers and operator meeting points. Confirm SIM/eSIM compatibility and the price of a working local plan rather than assuming roaming will function.
Language
English is an official and widely used administrative language. Local languages include Chuukese, Kosraean, Pohnpeian, Yapese and others across outer atolls. Learn place names and greetings, ask permission before entering village property or photographing people, and do not treat the four states as one interchangeable culture.
Insurance
Choose travel insurance that explicitly covers scuba at your intended depths, wreck/overhead or technical diving if relevant, freediving if planned, medical evacuation, trip disruption and onward hospital transfer. Check geographic and activity exclusions, the operator's emergency plan and the insurer's 24-hour contact process. State hospitals cannot be assumed to provide definitive decompression treatment.
Packing list
Pack lightweight tropical clothing, a rain shell, sun protection, mosquito repellent, reusable bottle, modest village clothing, sandals plus closed-toe trail shoes, waterproof bags and personal prescriptions. Divers should bring a dependable mask, dive computer, SMB and appropriate protective clothing; photographers need charging adapters, spares and secure floatation. Bring cash, passport copies, offline records and enough essential items for airline delays.
