Ngerukewid Islands

The Ngerukewid Islands sit at the southern edge of the Rock Islands lagoon, past the main cluster of formations that the day boats work, in a zone where the lagoon shallows drop away to deep open-ocean blue and the forested limestone outcrops get larger, less mushroom-shaped, more genuinely rocky and windswept. Very few dive boats come this far south. The only visitors are those who make a deliberate effort to find a boat willing to go — which usually means a private charter from Koror, or persuading a kayak outfitter to let you make the overnight crossing, or occasionally joining a liveaboard that includes the southern lagoon in its itinerary. The effort is the price of the quiet, and the quiet is worth it.

I reached the Ngerukewid group on the third day of a private boat charter that I’d booked partly because I’d already done the standard circuit of Blue Corner, German Channel, and Jellyfish Lake and wanted to know what the southern edge looked like. The skipper, who had been running boats in this lagoon for eighteen years, said most people didn’t want to go that far because there was “nothing there.” He meant no resort facilities, no marked snorkel spots, no parasol-and-deckchair beach. What there was, instead: nesting frigatebirds in the canopy of the larger islands, their call a sound like a creaking gate amplified through hollow bone; water of a blue so dark and deep that it registered differently than the aquamarine of the central lagoon, more serious, more oceanic, carrying the weight of the open Pacific at its edge; and a reef along the outer wall of the southernmost island where the coral has the density and age that comes from receiving very few kicking fins.

We anchored in a small cove on the largest island and I swam the outer reef alone in the early afternoon, which I recognized as mildly reckless given the current — the water moving around the southern tip of the island was decisive in a way that required attention. The coral there was extraordinary: table formations the size of dining tables, fan corals turning in the current, a density of small reef fish feeding in the water column that I associate with very healthy, very undisturbed systems. A Napoleon wrasse the size of a small refrigerator appeared at about twelve meters and hovered, watching me with that characteristic expression of dignified contempt. He had clearly decided I was not interesting and departed after thirty seconds.

At dusk, anchored in the cove with the skipper making rice on a small gas stove in the stern, the nesting frigatebirds above us settling into the trees with their creaking calls, I felt the particular satisfaction that comes from being somewhere that required effort to get to and that rewards the effort with something specific and real, not just with remoteness as an abstraction. The southern lagoon had its own atmosphere — heavier, quieter, older-feeling than the tourist circuit. The limestone looked different too: darker on the waterline, with more biological crust, as if it had been slowly accumulating something for centuries without disturbance.

The stars that night were the stars of the open Pacific, which is to say they were the kind of stars that make you aware that most of your life you live under too much light.

When to go: The southern lagoon is best in dry season (November through April) when current conditions are more predictable and the outer reef visibility is at its peak. The Ngerukewid group is a full-day trip at minimum from Koror; an overnight on a charter boat is the proper way to experience it. Access requires a private charter or liveaboard — there is no regular tour service. Check current restrictions with operators; parts of the southern lagoon may have seasonal conservation closures.
