SEA & ISLANDS
N 6°53′ / E 158°13′ — POHNPEI, FSM
Inside the reef and beyond — a journey through two shades of blue.
Pohnpei is wrapped in a barrier reef of coral. Inside lies a lagoon so calm it barely ripples; outside, the open ocean plunges abruptly into deep indigo.
Between these two blues, white-sand islets and small atolls are scattered like stepping stones. Run by boat from one to the next, and you meet a completely different sea at every stop — that is how Pohnpei is meant to be traveled.
PLATE 00—The Reef Edge
Ocean swell breaks on the reef; inside, the lagoon lies still.
SNORKELING
Every journey starts here
A fish paradise, just below the surface.
Sheltered by the barrier reef, Pohnpei's lagoon is clear and calm all year round. Even hesitant swimmers can float at ease over coral gardens crowded with anemonefish and butterflyfish.
The best time is the incoming tide, when clear ocean water floods the lagoon. The same spot can transform completely with the tide — and taking you to the day's best water is exactly what your captain is for.
Snorkel sets and life jackets are available on board
ANT ATOLL
Southwest — about an hour by boat
How many blues are there?
White sand melts into blue with no line to divide them. Stand before Ant Atoll's endless gradient and you catch yourself wondering just how many shades of blue exist. Thirteen islets in a UNESCO Biosphere Reserve — the paradise we proudly call Pohnpei's No.1 beach.
And snorkeling the single passage that joins lagoon and open ocean is, without hesitation, Pohnpei's No.1 spectacle: riding the tide through a blue canyon patrolled by barracuda and reef sharks. Then finish with a barbecue on that white-sand beach — in a setting like this, it is simply too good for words.
Landing requires the owners' permission (arranged on our tours)
PAKIN ATOLL
Northwest — across the open ocean
Adventurers wanted.
If Ant Atoll is the ultimate tropical escape, Pakin is the ultimate adventure. There is no passage here for larger boats: in the brief window of high tide you slip across a gap in the reef by small boat — or swim over the reef yourself. That thrill becomes an experience you will never forget.
Beyond the reef wait a beautiful beach and coral gardens without end — a forest of branching coral, home to clouds of colorful fish. When the incoming tide brings open-ocean water, visibility passes thirty meters — and that blue is known only to the challengers who cross the sea. Which is exactly why Pakin looks so special from the boat ride home.

NAHLAP ISLAND
The southwest lagoon, by road and boat
The easiest island holiday on the lagoon.
Nahlap, in the lagoon off Pohnpei's southwest coast, is an island retreat dotted with cottages and traditional nahs. Stretch out on white sand, snorkel the reef right off the beach — with canoes, waterslides and rope swings besides, it is the favorite island for families.
Just off the beach, the reef plunges into a deep drop-off, so shallow play and serious water live side by side at one island. And in the evening, the sunset that sets the lagoon aglow is a specialty all its own.

BLACK CORAL ISLAND
The far southwest, beside Kehpara Pass
A sand islet inside a marine sanctuary.
At the southwest corner of the barrier reef, beside Kehpara Pass, Black Coral is a small coral islet inside a marine protected area. Shaded footpaths wind neatly across the island, and simple wooden huts make it a quiet hideaway for camping.
The eastern beach and the pass to the north offer superb snorkeling: whitetip and blacktip reef sharks, and with luck, spotted eagle rays. Seasonal closures still protect these waters — a place to feel how a sea stays rich precisely because it is guarded.
Sanctuary rules limit the seasons when we can visit
DAULELE ISLAND
A tiny islet offshore
Nothing here. That is the luxury.
Run offshore by boat and a deserted islet appears: white sand, a single palm-thatched hut, and nothing else. Walking all the way around takes only minutes. What Daulele offers is 360 degrees of transparent sea and the bright fish that swim its reef.
Picnic and snorkel through the day; watch the sunset from a beach with no one else on it; stay into the night and the sky fills with stars. A day with nothing added often becomes the most vivid memory of the trip — that is this island.
And below the surface, the coral here is extraordinary. Thickets of branching coral fill the shallows, alive with small, brightly coloured fish — it is one of the prettiest snorkelling spots in all of Pohnpei.
On land: a shaded path and a palm-thatch hut.

LENGER ISLAND
Minutes from Kolonia harbor
Where history sleeps beneath the blue.
A short boat ride from Kolonia harbor, you step ashore on Lenger at the remains of a Japanese seaplane ramp — an island where the sea and history intersect. In the jungle rest gun batteries, magazines, and underground fuel bunkers where bats now roost, quiet relics of the Japanese era.
People still live on Lenger today. Many of the relics stand close to homes or on private land, and they are not places anyone can simply walk into. A visit depends on greeting the island's families and receiving their permission, so a guide always accompanies you and leads the way with respect for the community's daily life.

WAR RELICS ON LENGER
Everything from here on is found on Lenger itself. On this small island, a short boat ride from Kolonia, the paths you walk double as paths back into the Japanese era.
SEAPLANE RAMP
Built around 1939 to haul seaplanes up out of the sea, its underwater slabs laid by divers. The Americans repaired it after the war and used it as their main airstrip; today, when the tide drops, the cracked concrete simply runs on into the lagoon.
OIL TANK
A steel crude-oil tank on the island's south side at Pahnkamal. Two once stood here; the larger was dismantled in the 1970s. You can step inside where the lower panels have gone, and the ladder to the manhole in the roof is still in place.
STORAGE CAVES
Four caves dynamited into the hillside, the deepest running 28 metres back. Water stands underfoot and swiftlets nest in the ceilings — you go in by torchlight, into air that turns suddenly cool.
MAGAZINE
A row of small concrete chambers, their rusted steel doors still hanging on their hinges after eighty years. Earth was heaped over the roof to hide the whole thing from the air.
ANTI-AIRCRAFT BATTERY
Two anti-aircraft positions crown Dolen Lenger, the island's 77-metre hill: concrete rings ringed by stone-and-earth revetments, where 8 cm naval dual-purpose guns once sat. The guns were taken away after the war, leaving only the magazines — nine at one station, six at the other.
COASTAL GUN
Four gun stations face the sea. On the 15 cm gun lying on its side you can still read "No. 12810 1900" — said to be an Armstrong-Whitworth piece. The 15 cm gun up on Sokehs Ridge is said to have started out here on Lenger.
CONCRETE PLANT
The plant brought in to drive the caves: three concrete mixers, a Yanmar diesel engine, 610 mm gauge rail lines for carrying out the blasted rock, and a rock-crusher. Vines and tree roots are taking the gearwheels back, a little more each year.
SURVEY MARKER
Brush the fallen leaves away by hand and four characters rise out of the stone — 經緯度測點, "latitude and longitude survey point". A quiet record that this island once carried a surveyor's benchmark.
Most of the relics sit on islanders' private land. Please never enter on your own — visit only with a guide.
AND MORE
A famed channel where manta rays gather, at its best from January to April. Snorkelers, not only divers, sometimes meet their graceful glide.
At the lagoon's rim the bottom falls away into open ocean. Even peering down from the boat, the gradation from emerald into indigo takes your breath away.
The ride home across a mirror-still lagoon at dusk, as sky and sea slowly dissolve into amber — the tour's final reward.
With no town lights, island nights brim with stars. With luck, you will find the Southern Cross hanging just above the horizon.
No photograph carries this water's clarity, the wind, or the quiet. Come by boat and see both blues — inside the reef and beyond — for yourself.
Pohnpei Ocean Cruise reads the day's conditions and your wishes, and takes you to the finest water of the day.
