Blue Lagoon
Geothermal spa on the Reykjanes peninsula. Booking terms, tickets and hours are covered in the Blue Lagoon guide.
Hot Springs
From geothermal spas like the Blue Lagoon to wild highland rivers, Iceland's hot springs are scattered across every region. Access and facilities vary a lot.
The best hot spring in Iceland depends on the bathing you want: staffed spas and pools such as the Blue Lagoon, Secret Lagoon near Flúðir, Hvammsvík on Hvalfjörður and Earth Lagoon Mývatn, or a marked walk to the Reykjadalur hot river near Hveragerði. Only designated bathing places are safe to enter; geothermal areas such as Deildartunguhver and Gunnuhver are scalding and are for viewing only.

Hot springs in Iceland fall into four broad groups: managed geothermal spas, historic pools, natural hot rivers and streams, and geothermal areas that are for viewing only. Krauma, a spa in West Iceland near the boiling Deildartunguhver spring, has six baths, five warm and one cold. Krauma (source checked 2026-11-03) Operators set hours and prices, while natural sites have no staff, so facilities vary widely.

Two of the historic pools have documented dates. Secret Lagoon, known locally as Gamla Laugin, describes itself as the oldest swimming pool in Iceland and says it was made in 1891 at Hverahólmi, a geothermal area near Flúðir. Secret Lagoon (source checked 2026-11-03) Seljavallalaug was built in 1923 and has been a protected structure since 2006, according to Minjastofnun Íslands (the Cultural Heritage Agency), whose record gives no admission or water-quality information.

Iceland’s natural hot springs are safe to bathe in only at designated bathing places; unmarked springs, mud pots and steam vents can be boiling, and the ground around them can be fragile. At Gunnuhver on the Reykjanes peninsula, Visit Reykjanes reports that temperatures of more than 300 °C have been recorded and tells visitors to stick to the marked paths.

“Hydrogen sulfide has a strong smell and irritates the lungs, eyes, mouth and nose.”
Icelandic swimming pools and staffed geothermal spas expect a full wash before you enter the water. The City of Reykjavík tells pool guests they are “required to shower naked and wash thoroughly with soap” and to put on swimwear afterwards. City of Reykjavík (source checked 2026-11-03) Natural sites may have no showers, so bathe there without soap and keep their water clean.
Admission at Iceland’s hot spring spas differs by operator in price, age rules and changing facilities. Hvammsvík on Hvalfjörður lists a price range of 5,900 to 15,100 ISK by package and admits guests 10 or older, while Secret Lagoon near Flúðir lists 4,500 ISK for adults aged 15 and older. Hvammsvík (source checked 2026-11-03) Secret Lagoon (source checked 2026-09-10) Package names and inclusions change, so confirm on the operator’s booking page.

A lower ticket price can mean a different changing arrangement or an extra towel charge. Hvammsvík separates open showers in its Natural package from private showers in Classic; its minimum age is ten. Earth Lagoon Mývatn includes private showers in Essential and adds a towel and drink in Signature.
For families, Secret Lagoon charges for children aged fourteen and under and limits accompanying children per adult. For a small natural pool, Hrunalaug uses a 90-minute visit and admission without reservations, according to its operator’s page as checked 10 September 2026. Hrunalaug (source checked 2026-09-10) Check these terms before choosing solely from photographs. GeoSea’s prices are in the GeoSea guide.
Current details are linked and dated in each guide. These comparisons use Hvammsvík, Earth Lagoon, Secret Lagoon and Hrunalaug operator information checked 10 September 2026; the Hvammsvík and Earth Lagoon prices and hours were re-read on the operators’ pages on 3 November 2026, and the Hrunalaug terms have not been re-checked since September.
Reykjadalur, a geothermal valley near Hveragerði in South Iceland, has a warm river you can bathe in after a walk. Hveragerði’s hiking leaflet says it is a 3.5 km hike to the hot river on a marked trail. Visit Hveragerði leaflet (source checked 2026-09-10) Visit South Iceland adds: “The trail by Reykjadalur can be closed, so it’s good to check the conditions before going.” Visit South Iceland (source checked 2026-11-03)
Visit South Iceland describes the river as warm enough for bathing along part of its length, so the temperature depends on where you sit, and it points visitors to Safetravel.is to check whether the valley is open. The Reykjadalur guide covers the walk in more detail.
Managed hot springs in Iceland such as Secret Lagoon and Earth Lagoon Mývatn list daily opening hours in winter, while highland springs depend on seasonal roads. Secret Lagoon lists winter hours of 10:00 to 19:00 from October 1 to May 31, Secret Lagoon (source checked 2026-09-10) and Earth Lagoon Mývatn lists 12:00 to 22:00 daily. Earth Lagoon (source checked 2026-11-03) At Landmannalaugar, Parka’s 2026 rule requiring booked parking for self-drive arrivals ran from June 20 to September 13. Parka (source checked 2026-09-10)
The routes to Landmannalaugar and to Víti at Askja are highland F-roads; check Vegagerðin (road.is) for road status and Safetravel for alerts before planning either trip. Do not assume bathing in Víti is permitted. Vatnajökull National Park says the descent into Víti is slippery and that rock and mud slides may occur.

Deildartunguhver in West Iceland is a hot spring for viewing, not bathing, because its water comes out at boiling point. Krauma, the spa beside it, says Deildartunguhver has the highest flow rate of any hot spring in Europe, pumping 180 liters of 100 °C (212 °F) water per second. Krauma (source checked 2026-11-03) Visitors who want to bathe can use the warm baths at Krauma, near the spring.
Krauma is near Deildartunguhver at Reykholt on road 50, 97 km (60 miles) from Reykjavík, according to the operator. Krauma (source checked 2026-11-03) The Deildartunguhver guide and the Krauma guide cover both stops.
Planning help
Quick answers with safety notes where it matters.
Use designated bathing places. Unmarked springs may be boiling, and the ground around vents can be fragile. Do not touch an unknown spring to test it or step off a marked path to reach it. Keep children close and obey any access restrictions.
Some geothermal areas release hydrogen sulfide, which has a rotten-egg smell. The Icelandic Meteorological Office says hydrogen sulfide irritates the lungs, eyes, mouth and nose. Stay on marked paths, and if you feel dizzy or nauseous near a geothermal area, move to fresh air immediately.
Secret Lagoon publishes both winter and summer opening hours, and Earth Lagoon Mývatn lists daily hours, so managed pools can be visited in any season. Highland springs such as Landmannalaugar can be reached only while the seasonal highland roads are open; check Vegagerðin (road.is) and Safetravel for current road status before planning.
Bring a swimsuit, quick-dry towel, waterproof bag for electronics, and water shoes for rocky river beds. For remote springs, pack snacks and water. Leave no trace: carry out all waste.
At staffed pools and spas, wash before entering: the City of Reykjavík requires pool guests to shower naked and wash thoroughly with soap before putting on swimwear. Natural sites may have no showers; do not add soap to their water. Respect admission rules on private land: Hrunalaug has a set entry fee and visit limit rather than an optional donation.
