An archipelago beyond compare
Indonesia is a spectacular mosaic of 18,307 islands, a number revealed in a 2002 survey by the National Institute of Aeronautics and Space (LAPAN). Though rising sea levels and climate change spark ongoing debates about the exact count, the CIA World Factbook suggests 17,508 islands. Nevertheless, one thing remains certain: Indonesia reigns as the largest archipelago on Earth. This vast archipelago holds endless treasures and boundless surprises at every corner, from hidden islets fringed with swaying palms to towering, mist-shrouded volcanoes rising from the turquoise sea.
A sanctuary for endangered wonders
Ranked among the world’s 17 “megadiverse” countries by Conservation International, Indonesia is a living Eden, sheltering over 100 endangered species. This lush paradise is teeming with unique wildlife, many of which exist nowhere else on the planet which adds a nod to the country as the Lost World of Asia. Among these extraordinary creatures are the elusive Sumatran Tiger, the mystical Komodo Dragon, the endangered Sumatran Rhinoceros, the gentle Orangutans, and the Anoa—the world’s tiniest buffalo. Despite occupying only 1 percent of the Earth’s landmass, Indonesia’s rainforests are a botanical treasure chest, home to 10 percent of the world’s plant species, 12 percent of mammal species, and 17 percent of all known bird species.
Only place to encounter the world’s largest lizard
Speaking of endangered species, the Komodo Dragon is found exclusively on five Indonesian islands—Komodo, Rinca, Flores, Gili Motang, and Padar—where it roams the wild, untamed landscapes in solitude and majesty. This is the largest and most fearsome lizard on Earth that can reach lengths of up to 3 metres and weigh a staggering 150 pounds. With its venomous bite and carnivorous appetite, this formidable predator can bring down prey far larger than itself—humans included.
Realm of volcanoes and natural wonders
Indonesia claims the title of having the third-largest number of volcanoes in the world, with 139 in total—trailing only the United States and Russia. A visit to Mount Bromo’s summit offers a surreal experience: standing on the edge of the world, looking out over landscapes that seem to belong to another planet. But the wonders don’t end there. Indonesia is also home to Lake Toba in Sumatra, the world’s largest volcanic lake that stretches 100 kilometres long, 30 kilometres wide, and plunges to depths of 500 metres.
Tallest island peak on earth
Puncak Jaya, also known as Mount Jayawijaya, is the crowning jewel of Papua Province and the tallest island peak on Earth, towering an impressive 4,884 metres above sea level. Here, amidst the tropical splendour of Indonesia, you’ll find snow-covered peaks—a stunning contrast to the lush, sun-drenched landscapes that define the rest of the country.
Wealth of UNESCO World Heritage Sites
Indonesia, with its rich cultural heritage and diverse natural landscapes, is home to eight UNESCO World Heritage Sites, each more breathtaking than the last. From the ancient grandeur of the Borobudur and Prambanan Temple Compounds in Yogyakarta to the unspoiled beauty of Komodo National Park and the Tropical Rainforest Heritage of Sumatra, Indonesia’s treasures are boundless. Bali’s philosophical Subak System, the primordial Sangiran Early Man Site, and the uncharted wilds of Lorentz National Park in Papua round out this cultural and natural legacy, offering visitors an extraordinary journey through time and nature.
World’s largest flower blooms
In the dense rainforests of Sumatra, the Rafflesia arnoldii unfurls as the largest individual flower on Earth. This rare and captivating flower, with its five vibrant petals, can reach up to 1 metre in diameter and weigh an astonishing 10 kilograms. Known as the “Corpse Flower” for its overpowering scent of rotting flesh, it is a fleeting marvel—blooming only for a few short days after months of slow growth. Though elusive and tricky to find, its awe-inspiring presence is worth every effort to seek it out.
