Best said early. The capital, Palikir, is a group of administrative buildings with no urban fabric, and the largest settlement, Kolonia, is a functional town. Nobody comes for the cities.
01 A high island in a sea of atolls
Mount Nanlaud approaches 800 metres, and from there to the coast lies a massif of ridges, valleys and forest. Around it, a narrow plain, mangroves and a lagoon closed by a barrier reef.
That verticality is what separates Pohnpei from its neighbours. Within a few hundred kilometres almost everything is flat atoll; here there is gradient, rivers, waterfalls and mountain forest.
It is also what brings the rain: 5,202 millimetres a year on the coast and estimates above 8,000 in the interior. You will get wet, and that is the trip's entry condition.
02 The main plan is Nan Madol
On the east coast, beside the island of Temwen, there are ninety-two artificial islets built on the reef from basalt columns and coral fill, separated by canals. They were raised between the twelfth and seventeenth centuries and abandoned around 1628.
It has been World Heritage since 2016 and, in practice, it is why most visitors come to Pohnpei. A long half-day, with a local guide, footwear that copes with mud and coral, and the tide checked beforehand.
Do not expect a cleared site. Much of it is under mangrove and rainforest, and access crosses privately held land, so it is arranged from Kolonia rather than on your own.
03 Waterfalls, mangrove and forest
With that much water, the island's rivers run all year and the interior waterfalls are the second essential plan. You drive to a point and then walk, almost always through mud.
The coast is not sand but mangrove along much of its perimeter, which makes it interesting to explore by boat and impractical for swimming. The beaches are on lagoon islets, not on the main island.
And there is the reef. Diving here is good and barely exploited, but there is no established industry: it is arranged as you go and depends on who is available that day.
04 Where you sleep and what you eat
Accommodation is concentrated in Kolonia and at a few coastal points, in a range from simple to very simple. There are no beach resorts and no luxury offer, and it is worth booking ahead because the rooms are few.
At the table, what the island produces rules: fish, yam, taro, breadfruit and banana, with imported rice and tinned goods. The local kitchen is about stews and earth ovens rather than menus.
One logistical warning: flights are few and chained with other islands, so a cancellation can cost you days. Leave margin before any important connection.
05 How to build four days
Day one: Kolonia and the road out to Palikir, stopping at the capital's compound to see what it is. A good half hour is enough, and the rest of the day serves to get your bearings and line up guides.
Day two: Nan Madol, with the tide checked and the whole morning available. It is the outing that justifies the trip, and it should not be squeezed into an afternoon.
Days three and four: interior and water. A waterfall with a walk, a run through the mangrove or out to the reef, and a spare day for rain, which here is not a possibility but a certainty.
