The steamy story behind Iceland’s most common place name
If you’ve ever looked at a map of Iceland, you’ve probably noticed something curious: an awful lot of towns, bays, and valleys seem to share the same first syllable. Reykjavík. Reykjanes. Reykholt. Reykjadalur. Reykjahlíð. The list goes on and on. It’s not a coincidence, and it’s not a case of unimaginative namers running out of ideas. The answer is written into the very ground beneath Iceland’s feet — and once you understand it, you’ll never look at the country’s map the same way again.
It All Comes Down to Smoke
The word “reykja” comes from the Old Norse word “reykr,” meaning smoke or steam. When the first Norse settlers arrived in Iceland in the ninth century, they found a landscape unlike anything they’d seen before: hillsides and valleys where wisps of vapor rose steadily from the earth, even in the depths of winter. To them, it looked exactly like smoke curling up from a fire. So, quite sensibly, they named these places after what they saw — the “smoking” land.
Of course, we now know that what those settlers were actually looking at wasn’t smoke at all. It was steam, rising from geothermal hot springs, fumaroles, and heated ground — a direct result of Iceland sitting on top of one of the most volcanically active regions on Earth, right along the Mid-Atlantic Ridge.
The Most Famous Example: Reykjavík
Iceland’s capital city owes its name to this exact phenomenon. According to Icelandic sagas, Ingólfur Arnarson, traditionally credited as the first permanent Norse settler of Iceland, threw his high-seat pillars overboard as he approached the coast and vowed to settle wherever they washed ashore. When his men found them, they landed at a bay wreathed in steam rising from nearby hot springs. He named the settlement Reykjavík — “Reykja” (smoke) plus “vík” (bay) — literally, “Smoky Bay.”
It’s a fitting bit of irony that the capital of one of the world’s cleanest, greenest energy economies was named after something people once mistook for smoke. Today, that same geothermal activity heats homes, powers cities, and fills the country’s famous geothermal pools — including the Blue Lagoon.
A Naming Pattern Repeated Across the Country
Reykjavík is just the beginning. Because geothermal activity is scattered across Iceland — not confined to one region — settlers encountered “smoking” ground again and again as they explored and claimed new territory. Each time, many gave the same practical, descriptive name. That’s why you’ll find “Reykja” show up throughout the country, often combined with a second word describing the landscape:
- Reykjanes (“Reykja” + “nes,” meaning peninsula) — the steaming peninsula in the southwest, home to volcanic fields and the Blue Lagoon.
- Reykjadalur (“Reykja” + “dalur,” meaning valley) — a geothermal valley near Hveragerði famous for its warm river, perfect for a soak after a hike.
- Reykholt (“Reykja” + “holt,” meaning wooded hill or knoll) — a historic settlement in West Iceland, once home to the medieval scholar Snorri Sturluson.
- Reykjahlíð (“Reykja” + “hlíð,” meaning slope or hillside) — a village by Lake Mývatn, surrounded by some of Iceland’s most dramatic volcanic scenery.
In every case, the logic is the same: early settlers named what they saw, and what they saw was steam rising from the earth.
Why This Matters for Travelers Today
For visitors, this naming pattern is more than just a linguistic curiosity — it’s practically a treasure map. Any place name beginning with “Reykja” is a strong hint that there’s geothermal activity nearby: hot springs, steam vents, or naturally heated rivers. If you’re planning a trip to Iceland and you see “Reykja” on a map, it’s often worth a closer look. It might just lead you to a hidden hot spring, a quiet valley made for a warm soak, or a fascinating glimpse into the volcanic forces that shaped the entire island.
A Name Rooted in the Land Itself
What makes Iceland’s place names so special is how directly they reflect the natural world. Long before maps, geothermal science, or tourism, the earliest settlers were simply describing what they encountered — steaming valleys, smoking bays, and hillsides that seemed alive with vapor. Centuries later, those same names still tell that story every time they’re spoken aloud.
So the next time you spot “Reykja” at the start of a name on your Iceland itinerary, you’ll know exactly why it’s there — and quite possibly, what you’ll find when you get there.
