Iceland's Geothermal Areas: How to Visit With Respect

Steam, sulphur and safety: a practical guide to Iceland's geothermal sites, from the famous to the fuss-free, with the rules that keep them open.

The Big Draws: Geysir, Strokkur and the Crowds

Geysir geothermal area in Haukadalur valley is the obvious first stop on the Golden Circle, about 100km and 1hr 20min drive from Reykjavík on Route 35. Strokkur erupts every 5–10 minutes, so you rarely wait long. The site is free and open all year, but coach tours arrive mid-morning to early afternoon; come before 9am or after 4pm for smaller crowds. Stay behind the ropes: the water is near boiling and the ground can be fragile. There are toilets and a café at the visitor centre, but no swimming here.

Nearby, the town of Flúðir (30km, 25min) has two lesser-known pools: Gamla Laugin, a natural hot spring with a wooden deck, and the Secret Lagoon, which has a similar setting but a higher entry fee (around ISK 3,000–4,000). I would book the Secret Lagoon only if you want changing rooms and a bar; otherwise, Gamla Laugin is simpler and cheaper. Both are far less crowded than the Blue Lagoon and make a good add-on to the Golden Circle without a detour.

Beyond the Golden Circle: Mývatn, Landmannalaugar and the West

In the north, the Mývatn region (about 4hr 30min drive from Reykjavík on Route 1, or a 45min flight to Akureyri plus 1hr drive) has several geothermal spots. Hverir at Námafjall is a hissing, steaming hillside with bubbling mud pots; entry is free, and it is best visited on a calm day (wind blows the steam and smell). The Mývatn Nature Baths (around ISK 4,500–5,500) are less crowded than the Blue Lagoon and have a similar milky-blue water. I would book a hotel in Reykjahlíð for two nights to cover Hverir, Dimmuborgir and the baths without rushing.

Landmannalaugar in the Highlands is only accessible in summer (roughly mid-June to mid-September) and requires a 4x4 or a bus from Hvolsvöllur (about 2hr). The natural hot river here is free, but there are no changing facilities, and the ground is sensitive. The Westfjords' Hólmavík area has the Drangsnes hot pots (free, three small tubs by the sea) — a 2hr drive from Hólmavík town. These are simple, unsupervised and wonderful, but bring your own towel and respect the locals who use them daily.

The Rules That Keep These Places Open

Iceland's geothermal areas are active and fragile. Stay on marked paths: the crust can be thin and scalding water lies just below. At Hverir and Geysir, the ground is clay and can be slippery; wear sturdy shoes. Never touch the water in natural springs unless it is a designated bathing area — temperatures can exceed 80°C. Do not throw coins or objects into pools; they clog the vents and damage the silica formations. And do not fly drones over protected areas without permission; it disturbs birds and other visitors.

Swimming in natural hot springs is a privilege, not a right. At Landmannalaugar, use the marked river area and do not soap up in the water; biodegradable soap still harms the ecosystem. At the Drangsnes pots, rinse off before entering and leave the area as you found it. Many sites are on private land; obey signs and gates. If a site is closed, it is usually for safety or repair — do not ignore barriers. The Icelandic Environment Agency and local municipalities maintain these areas; your respect keeps them free and open.

Where to Base Yourself and When to Go

For the Golden Circle and southwest, base in Reykjavík (hotels from around ISK 20,000–30,000 per night) or in Hveragerði (45min drive, guesthouses from ISK 15,000). Hveragerði itself has a geothermal park and the Reykjadalur hot river hike (about 3km, 1hr each way) — free and stunning, but bring a towel and change of clothes. For the north, Akureyri is a good hub (flights from Reykjavík 45min, or 4hr 30min drive) with hotels from ISK 18,000–25,000. Book ahead in July and August; prices rise and availability drops.

Best months: June to August for all sites, including the Highlands; September and October for fewer crowds and cheaper hotels, though some Highland roads close. Winter visits to Geysir and Mývatn are possible but check road conditions (road.is) and daylight (4–5 hours in December). I would skip the Blue Lagoon if you are on a budget and visit Mývatn Nature Baths instead — similar experience, lower price, fewer people. And always book your hotel through a local partner to get up-to-date advice on closures and conditions.

Questions, answered

Can you swim in the geothermal areas?

Only in designated bathing spots like the Secret Lagoon, Mývatn Nature Baths, or Landmannalaugar's hot river. Natural springs elsewhere are often scalding and off-limits. Always follow signs.

Do I need a 4x4 to visit Landmannalaugar?

Yes, unless you take a bus. The F208 road is rough and requires a 4x4. Buses run from Hvolsvöllur in summer (mid-June to mid-September).

Is Geysir free to visit?

Yes, the Geysir geothermal area is free and open all year. There is a visitor centre with café and toilets. Parking may have a fee.

What should I wear for geothermal hikes?

Sturdy, waterproof shoes and layers. Ground can be slippery and steam can be hot. Avoid flip-flops. Bring a towel if you plan to bathe.

Are there changing facilities at natural hot springs?

Often not. At Landmannalaugar and Drangsnes, there are basic or no facilities. Come prepared to change discreetly or bring a towel and robe.

Can I visit geothermal areas in winter?

Yes, but check road conditions and daylight. Some Highland sites are inaccessible. Geysir and Mývatn are open year-round but icy paths require care.

Why is the Blue Lagoon so expensive?

It is a commercial operation with high demand. Entry is around ISK 8,000–10,000. For a similar experience at lower cost, try Mývatn Nature Baths or the Secret Lagoon.

Where should I stay to explore geothermal sites?

Reykjavík for the Golden Circle, Hveragerði for the hot river, Akureyri or Reykjahlíð for Mývatn, and Hólmavík for the Westfjords. Book ahead in summer.
