Why visit Kiribati, three countries inside one.
Kiribati is functionally three destinations and the right itinerary picks one focus. Tarawa atoll is the country's political and population heart, with South Tarawa (Bairiki, Bikenibeu, Bonriki) hosting most of the country's 115,000 people on a thread of land you can drive end-to-end in 90 minutes. The reason most visitors come to Tarawa is the Battle of Tarawa: in November 1943 the 2nd Marine Division stormed Betio Island in one of the bloodiest amphibious assaults in US history, 1,000 Marines and 4,500 Japanese defenders killed in 76 hours. The battlefield is essentially intact in ways no European WWII site is: Sherman tanks rust on the lagoon-side reef flats, Japanese 8-inch Vickers naval guns still point seaward from Red Beach pillboxes, and the Betio Memorial honors both sides. There is a reason historians, veterans' families, and serious WWII travellers come specifically here. Christmas Island (Kiritimati) is the country's other major destination and a totally different proposition: at 388 km² it is the world's largest atoll by land area, sits east of the international date line (which is why this country is the first place on earth to see each new day), and hosts globally significant bird colonies, millions of nesting sooty terns, lesser frigatebirds, red-tailed tropicbirds, and masked boobies at Cook Island and the eastern lagoons. It is also one of the best bonefishing destinations on earth, with vast wadable flats and dedicated fly-fishing lodges that draw a small dedicated crowd from the US and Australia. Outer Gilbert atolls, Abemama, Tabiteuea, Butaritari, Marakei, are for travellers who want unmediated atoll life: traditional maneaba meeting houses, copra economies, and almost no infrastructure. Kiribati is also the country where you most directly experience the climate-change frontline; visits to seawall-construction sites and recently inundated graveyards are part of an honest itinerary.
