The Capital of Palau: Ngerulmud, Not Koror
Ngerulmud has held the title of national capital since October 7, 2006, when Palau's constitution required the government to relocate from Koror to Babeldaob, the country's largest island (CIA World Factbook, 2006). The complex, designed by the Hawaii-based firm Architects Hawaii Ltd., houses the Olbiil Era Kelulau — Palau's National Congress — along with executive offices and the judiciary, arranged around a central plaza.
There's no independently verified population figure for Ngerulmud itself, because it's a cluster of government buildings rather than a city. Any population number attached to "Ngerulmud" actually describes Melekeok State, which surrounds the complex. Confusing Ngerulmud with Koror is the single most common error in reference material about Palau — worth settling before the rest of the geography makes sense.
Why Palau Moved Its Capital From Koror in 2006
Koror served as Palau's de facto and later constitutional capital from 1981 until the 2006 move. The relocation to Babeldaob was written into Palau's constitution, driven partly by a desire to ease congestion in Koror and partly by the logic that the seat of government should sit on the country's largest landmass rather than its busiest one.
The move was administrative, not economic. Koror kept its role as Palau's commercial and residential hub; the shift only changed where the legislature and executive offices physically sit.
Koror: Where Travelers Actually Go
Koror remains Palau's largest city and holds most of the national population, along with nearly all of its hotels, dive shops, and restaurants. Roman Tmetuchl International Airport sits near Koror, so it's the arrival point for virtually every visitor, regardless of where the official capital technically is.
Boat trips to the Rock Islands, Jellyfish Lake, and the Blue Corner dive site all leave from Koror's docks — none of them depart from Ngerulmud. Travelers stacking a multi-day boat schedule around permit windows can check timing conflicts with the itinerary validator before booking. Koror is the practical answer to "where do I go," while Ngerulmud is the technical answer to "what is the capital."
How Many People Live in Palau
Palau's 2025 population was estimated at 21,947 using CIA Factbook methodology (CIA World Factbook, 2025). World Bank data, which generally follows UN population methodology, puts recent estimates closer to 17,600 (World Bank Open Data — Palau). The gap reflects differing census years and residency definitions, not a factual dispute — cite the source you're drawing from rather than treating one figure as universal.
Koror accounts for the large majority of residents in either estimate. Published population figures attached to "the capital" describe Melekeok State as a whole, not a city called Ngerulmud.
Where Palau Sits on the Map
Palau is an archipelago nation in the Micronesia subregion of Oceania, sitting west of the Philippines and north of Indonesia. In terms of continent, that places Palau in Oceania rather than Asia, despite its geographic proximity to Southeast Asia. It's one of the more remote stops in the Pacific, which is part of why flight logistics matter more here than in most destinations.
Palau's Islands and Land Area
Babeldaob is Palau's largest island and home to the capital complex. Further south, near Koror, sit the Rock Islands — a UNESCO World Heritage site made up of mushroom-shaped limestone islets rising out of turquoise lagoons. The archipelago spans more than 300 islands total, most of them uninhabited, with a combined land area of about 459 square kilometers (177 square miles), per the CIA World Factbook's geography data (CIA World Factbook).
Is Palau a US Territory?
Palau is not a US territory. It's an independent republic, sovereign since 1994, distinct from territories like Guam or American Samoa. The relationship with the US runs through a Compact of Free Association, which provides defense guarantees and economic assistance in exchange for US military access. Palau keeps its own government, currency use, and foreign policy. The Palau government's official portal outlines the Compact's terms directly.
Palau's economy leans on tourism and fishing as its main pillars, with Compact-linked financial assistance from the US supplementing government revenue (CIA World Factbook, 2025). Most jobs tied to tourism cluster in and around Koror, not near the capital complex.
Language and Religion in Palau
Palauan and English are the official national languages of Palau (CIA World Factbook, 2025). Sonsorolese and Tobian are spoken regionally within their respective states.
Religion in Palau
Palau's population is predominantly Christian, with roughly 47% Roman Catholic and 26% Protestant, reflecting periods of Spanish, German, Japanese, and American administration (CIA World Factbook, 2020). Modekngei, an indigenous Palauan faith blending local tradition with Christian elements, is practiced by a minority. A small Muslim community exists alongside other minority faiths.
Flag and National Symbols
Palau's flag, adopted in 1981, features a pale blue field with an off-center gold disk representing the moon — a symbol tied to local folklore and considered an auspicious time for harvest and ceremony.
Best Time to Visit Palau
The dry season, roughly November through April, offers the clearest underwater visibility for diving and snorkeling around the Rock Islands. The wetter season from May through October brings more rain and occasional storms, but also lower prices and fewer crowds.
Jellyfish Lake conditions and visibility shift seasonally, so it's worth pairing any diving plans with current reports from local operators rather than relying on calendar assumptions alone. Whatever the season, flights, permits, and boat departures all route through Koror — the official capital doesn't factor into trip logistics at all.
