Ever tried naming every country starting with the letter "I" in a rapid-fire trivia game? You probably hit the big ones immediately. Italy? Obviously. India? Of course. But then things get kinda fuzzy. Suddenly, you’re wondering if Ivory Coast counts (officially, it’s Côte d’Ivoire, so technically no) or if the Isle of Man is its own nation (it’s a Crown Dependency).
There are actually eight sovereign states that officially kick off with the ninth letter of the alphabet.
Geography is funny like that. We think we know the map until we actually have to list it out. From the volcanic ridges of Iceland to the sprawling archipelago of Indonesia, the "I" countries represent some of the most diverse climates and cultures on Earth. Honestly, it’s a weirdly eclectic group. You’ve got some of the world's most populous giants sitting right next to tiny island nations where sheep outnumber people.
The Heavy Hitters: India and Indonesia
Let’s talk about the big guys first. India is no longer just "one of" the most populated countries; it is the most populated. As of 2026, the demographics are staggering. We're talking about roughly 1.46 billion people. If you’ve never been, it’s a sensory overload in the best way possible. Most people think of the Taj Mahal, but the real magic is in the regional nuances. For instance, did you know that India has the world’s largest postal network? Or that it’s home to a village called Mawsynram, which is the wettest place on the planet?
Then you have Indonesia. This place is a beast. It’s the world's largest archipelagic state, made up of over 17,000 islands. People fly into Bali and think they’ve seen Indonesia. They haven't. They’ve seen one (admittedly beautiful) sliver. To really get it, you have to look at Java, where the capital is shifting from a sinking Jakarta to the new forest city of Nusantara. Indonesia is actually the most populous Muslim-majority nation, a fact that surprises many Western travelers who only associate the "I" countries with different religious roots.
The European "I" Duo: Italy and Ireland
Italy is basically the gold standard for travel. You know the vibes: pasta, ruins, and fast cars. But what most people get wrong about Italy is the regional divide. The north and south are practically different countries. While Milan is all sleek business and high fashion, Sicily is rugged, ancient, and operates on "island time." Also, a quick tip for your next trip: don't order a cappuccino after 11:00 AM. Italians think milk after a meal ruins digestion, and they will judge you.
Across the water, we have Ireland. Known as the "Emerald Isle," it lives up to the name. It’s green. Very green. But don't make the mistake of calling it part of the UK; the Republic of Ireland is a totally separate, independent nation. One of the coolest things about Ireland right now is the tech boom in Dublin, often called the "Silicon Docks." It’s this weird, charming blend of 1,000-year-old pubs and multibillion-dollar software headquarters.
The Middle Eastern Context: Iran, Iraq, Israel
This is where the "I" list gets complex. Iran is often misunderstood through a purely political lens, but its history is deep. We're talking about the cradle of the Persian Empire. The architecture in Isfahan is genuinely some of the most intricate in the world.
Iraq, similarly, sits on the land of ancient Mesopotamia. While it hasn't been a mainstream tourist hub for decades due to conflict, parts of the country—like the Kurdistan region in the north—have seen a trickle of adventurous travelers interested in the ruins of Babylon and the marshes of the south.
Then there’s Israel. It’s tiny. You could drive across it in a few hours. Yet, it’s one of the most intensely debated pieces of land in history. Beyond the religious significance of Jerusalem, the country is a massive tech hub. They basically invented the cherry tomato and the USB flash drive. It’s a place where you can float in the Dead Sea (the lowest point on Earth) in the morning and be at a high-tech startup conference in Tel Aviv by the afternoon.
The Outlier: Iceland
Finally, we have Iceland. It’s the rugged, cold cousin of the group. With a population of only about 398,000, it’s the most sparsely populated country in Europe. Iceland is a land of extremes. You have glaciers sitting on top of active volcanoes. In the summer, the sun doesn't really set. In the winter, you get maybe four hours of light, but you also get the Northern Lights.
A weird fact about Iceland? They don’t have mosquitoes. Not one. The climate is just erratic enough that the little pests can’t complete their life cycle. Honestly, that alone makes it worth the flight.

What to Keep in Mind for 2026 Travel
If you’re planning to visit any of these "I" countries this year, the landscape has changed. "Noctourism" is the big trend for 2026. Because of rising daytime temperatures in places like Italy and India, more travelers are opting for night-time tours of the Colosseum or late-evening temple walks in Varanasi.
Digital nomad visas have also become the norm. Italy and Indonesia have both streamlined their systems, making it way easier to work from a Tuscan villa or a beachfront shack in Lombok for six months at a time.
Quick Reference Table (The Prose Version)
Since a perfect table feels a bit too "bot-like," let's just break down the essentials.
- Iceland: Capital is Reykjavik. Use the Krona. No mosquitoes, lots of waterfalls.
- India: Capital is New Delhi. Use the Rupee. World's largest democracy.
- Indonesia: Capital is moving to Nusantara. Use the Rupiah. 17,000+ islands.
- Iran: Capital is Tehran. Use the Rial. Ancient Persian heritage.
- Iraq: Capital is Baghdad. Use the Dinar. Home of ancient Mesopotamia.
- Ireland: Capital is Dublin. Use the Euro. Famous for the "craic" and lush landscapes.
- Israel: Capital is Jerusalem. Use the Shekel. High-tech meets ancient history.
- Italy: Capital is Rome. Use the Euro. World leader in UNESCO World Heritage sites.
Actionable Insights for Your Journey
Before you go jetting off to an "I" country, do your homework on the local etiquette. In India, always use your right hand for eating or passing items. In Iceland, never, ever buy bottled water—the tap water is literally some of the purest on the planet. And in Italy, remember that "bar" usually means a place for coffee and a quick pastry, not just a place for a late-night drink.
The best way to experience these places is to look beyond the "top 10" lists. Go to the secondary cities. Visit Cork instead of just Dublin. Try Turin instead of just Rome. You'll find shorter lines, lower prices, and a much more authentic slice of life.
Check your passport validity now. Most of these countries require at least six months of validity remaining from your date of entry. If you're looking at Indonesia or India, make sure to apply for your e-Visa at least two weeks before departure to avoid any last-minute stress at the airport.

Start by mapping out your route based on climate. You don't want to be in Delhi during the peak heat of May, just like you might want to avoid Iceland in the dead of January unless you're specifically hunting the Aurora. Pick one "I" country, dive deep into its regional history, and you'll realize the letter "I" is just the beginning of the story.
