Attraction in Micronesia
Nan Madol is a UNESCO World Heritage Site comprising 92 artificial islands built from interlocking basalt columns in a lagoon off Pohnpei's eastern coast. Constructed between the 12th and 15th centuries as the ceremonial and political seat of the Saudeleur dynasty, its canals and towering stone walls are best explored by boat or kayak. The sheer scale of the construction, with individual basalt logs weighing up to 50 tonnes transported from distant quarries, continues to fascinate archaeologists.

Travel Guide
Entry requirements vary by passport. Check the requirements for your specific passport on the Micronesia page at Yoogo.
The Federated States of Micronesia uses the US dollar (USD) as its official currency. Cash is by far the most widely accepted form of payment, as credit card facilities are limited outside major hotels and a handful of shops in the main towns.
The Federated States of Micronesia is generally considered a safe destination with low levels of violent crime. Petty theft can occur, particularly in and around Weno on Chuuk, so standard precautions with valuables are sensible.
Inter-island travel within the FSM relies almost entirely on small aircraft operated by carriers connecting the four state capitals of Pohnpei, Chuuk, Yap, and Kosrae. Within each island, taxis are the main form of transport and fares are typically fixed and inexpensive.
The dry season from December to April generally offers the most settled weather, with calmer seas, lower rainfall, and excellent visibility for diving and snorkelling. The wet season from May to November can still be rewarding, with fewer visitors and lush green scenery, though typhoons are possible between July and October.
English is the official national language and is widely spoken in government, schools, and most tourist-facing businesses. Each of the four states also has its own indigenous language, including Pohnpeian, Chuukese, Yapese, and Kosraean, which remain in everyday use alongside English.
Travellers are generally advised to ensure routine vaccinations are up to date and to consider hepatitis A, typhoid, and hepatitis B vaccinations before travel. Medical facilities across the islands are limited, so it is wise to carry a personal medical kit and any prescription medicines you may need.
Tipping is not a strong cultural expectation in the Federated States of Micronesia, where hospitality is traditionally considered a communal duty rather than a service transaction. A small tip for excellent service in hotel restaurants or for dive guides is appreciated but not obligatory.
FSM Telecommunications Corporation (FSMTC) is the sole mobile network provider, offering 4G/LTE coverage in the main towns of each state. Airalo and a small number of other eSIM providers offer Micronesia data packs that run on the FSMTC network, providing a convenient option for travellers who prefer to avoid roaming charges.
Dress codes are important on several islands, particularly Yap and Kosrae, where modest clothing covering the thighs is expected when visiting villages. Asking permission before photographing people or entering private land is considered respectful, and accepting food or drink when offered is an important gesture of goodwill.
