Indonesia is the Biggest Archipelagic Country in the World
Indonesia is the world’s largest archipelagic country. According to the Indonesian Geospatial Information Agency (BIG), the country had 17,380 officially recorded islands in 2025. This number may change as islands are surveyed, named, and verified. The archipelago covers approximately 1.9 million square kilometres of land, stretching across a vast region between the Indian and Pacific Oceans. For updated figures, see the official Indonesian Geospatial Information Agency.
Indonesia recognizes five major islands- Borneo, New Guinea, Sumatra, Sulawesi, and Java, with the Maluku Islands and Nusa Tenggara as major groups. There are also smaller groups with sixty members in them. Some are under shared territorial rights, such as Borneo (with Brunei and Malaysia), Sebatik is co-owned with Malaysia, East Timor shares Timor, and Papua New Guinea has New Guinea.
There might be a bit of complication both geographically and politically. However, it still doesn’t change that Indonesia hosts the largest archipelago in the world, followed by the Philippines with 7,641 islands.
Making it a Cradle to Rich Biodiversity
It’s no surprise that Indonesia is the second wealthiest biodiversity hotspot. It ranks among the world’s megadiverse countries (only 17 of them!) and is the home to the third biggest rainforest next to Congo Basin and Amazon.
Indonesia is home to the reticulated python, the world’s longest living snake species. A specimen reportedly measuring 10 metres was found in Sulawesi in 1912, although this historical claim lacks sufficient supporting evidence. In January 2026, a wild reticulated python from Sulawesi was officially measured at 7.22 metres, setting a verified Guinness World Record. Learn more from Guinness World Records. The gigantic Corps Flowers, spanning up to 15 ft. tall and seven kg.-heavy, are also native here. And there’s no forgetting the legendary Komodo Dragons! It’s a country ready to surprise every nature lover with its 54 national parks, where five are across wetlands, nine cover the underwater world, and six are recognized as World Heritage Sites.
With the 3rd Longest Coastline
Running over 54,000 km long, Indonesia’s coastline is a cradle of beautiful beaches and diverse marine ecology. It’s sitting just next to Norway at more than 83,000 km and Canada with over 202,000 km. With the country’s alluring shores, some are even hailed as the best in the world!
Rendering it a Scuba Diver’s Paradise
Undoubtedly, diving in Indonesia is one of the ultimate diver’s dreams. With its geography, the vast waters inhibit over 2,000 reef fish species and 600 species of corals and serve as a route for 30 migratory marine mammals. It’s a treasure trove for every scuba diver and avid snorkeler!
Whether you’re treading the waters to see a wreck, checking out reef walls, or deep diving, there’s undoubtedly a treat for you in Indonesia. Some of the marine life forms you’ll encounter here are blue ring octopus, manta rays, sharks, turtles, and eels. It also hides the bony and heavy Mola-Mola. Famous and historic wrecks like USAT Liberty Meno Bounty and Glenn Nusa are also waiting for you. Today, the booming diving industry contributes to Indonesia’s economy and marine conservation. Whether you’re a newbie or an expert, there are over 50 dive sites in Indonesia to give you the adventure you crave!
It’s a Home to more than a Thousand Ethnic Groups
Indonesia is home to more than 1,300 recognised ethnic groups and hundreds of regional languages. Bahasa Indonesia serves as the national language and a common means of communication across the archipelago, while many Indonesians also speak Javanese, Sundanese, or other regional languages as their mother tongue. This remarkable linguistic diversity reflects the country’s long history of migration, trade, and cultural interaction.
Roughly 40% of the ethnic population are Javanese, followed by Sundanese, Malays, Bugis, and Batak. Manangkabau, Madurese and Betawi also form large groups. Most only have hundreds of people. There are no strict rules about the ethnic groups’ division, and some share practices and languages that can be confusing. For example, the Baduy are an indigenous Sundanese community in Banten, western Java, with distinctive traditions and customs. But overall, the rich culture of Indonesia is a match for its rich biodiversity!
And over a Hundred Active Volcanoes
Since Indonesia sits at the Pacific Ring of Fire, it’s a hotspot for volcanoes. One hundred twenty-seven are active in which Mount Merapi and Kelut are considered the most aggressive. Most of them belong to the 3,000 km-long Sunda Arc, tracing a path along Sumatra, Lesser Sunda Islands, Sunda Strait, Java, Nusa Tenggara, and Flores. It’s a volcanologist’s heaven on earth!
The most destructive and deadliest was the eruption of Krakatoa in 1883, which took more than 36,000 lives. The explosion was so loud that it even reached Perth. Mauritius and fifty more places around the world.
There’s Stable Weather All-Year Round
Indonesia is located near the Equator, making it a tropical paradise. Be prepared to experience a hot, humid, and wet climate. And since warm bodies of water surround it, the land remains almost the same temperature throughout the year, with minimal fluctuations.
Although temperatures remain relatively stable in most lowland areas, rainfall varies considerably throughout the year. Much of Indonesia experiences distinct wet and dry seasons shaped by the monsoons, while some eastern and equatorial regions follow different rainfall patterns. Therefore, the best season for travelling depends on the island and the activities you plan. However, some high-altitude places like the mountain ranges in Papua have cooler temps and are covered with snow.
Head Hunting was once a Thing in Indonesia
Taking the enemy’s head as trophy-eek! Well, at least it’s a thing of the past. Indonesia has its reputation for head hunters. They used to believe that bringing home a body part of the deceased would grant them the power to enslave the individual in the afterlife. Today, this ritual is still practiced in nonviolent ways in a harvest festival called pangngae. But! No beheading. Just coconuts were acting as substitutes (thank goodness!).
Some of the last surviving descendants of the notorious head hunters are in West Papua. These include the Dani Tribe, Yali Tribe, Asmat Tribe, Korowai Tribe, and Kombai Tribe. Borneo also has the Iban people, who still have some of the skulls on display.
But You’ll also find the Biggest Buddhist Temple Here
The UNESCO World Heritage site Borobudur is the world’s biggest Buddhist temple. Its base covers 403 ft. x 403 ft. and stands tall at 113 ft, with a total area of 2,118,880 ft.3. This magnificent Buddhist monument features 504 Buddha statues in total, including 432 around its square terraces and another 72 enclosed within the bell-shaped, perforated stupas on the upper circular terraces.
Borobudur attracts over five million visitors annually as the country’s most visited tourist attraction. It’s an architectural and spiritual masterpiece. A place anyone can marvel at its beauty and serenity!
Indonesia is the Largest Frog Legs Exporter
Shipping to Luxembourg, France, and Belgium, Indonesia is the biggest exporter of frog legs. France alone imports 4,000 tons of frog legs yearly! Known locally as kodok, prepare your appetite for some exotic cuisines you’ll never forget!
