Geothermal Areas
Hot springs, geysers and mud pots — access and safety warnings
Geysir (Strokkur)
Strokkur erupts every 6–10 min, up to 20 m. Geysir itself rarely erupts.
Hverir (Námafjall)
Mud pots and sulfur fumes. Vibrant yellow and red colors.
Krafla / Leirhnjúkur
Active volcano, hot lagoon and fissures. Last eruption 1984.
Deildartunguhver
Highest-flow hot spring in Europe — 180 l/sec. Heats Borgarfjörður.
Hveravellir
Geothermal area in the highlands between Langjökull and Hofsjökull. F-road.
Grænavatn
Green water from sulfur. Interesting to see, not for bathing.
Sulfur gas — H₂S
Geothermal areas can emit hydrogen sulfide (H₂S) which is toxic at high levels. Don't linger in depressions with heavy fumes.
Stay on paths and boardwalks. Avoid touching hot water or mud — geothermal areas can change suddenly.
Burn hazard
Water and mud can be over 90°C — even 300°C as steam. Skin can be severely burned.
Use paths, boardwalks and signs. Don't leave paths — the surface can be thin and hot underneath.
Do not bathe in hot springs or streams unless specifically marked as a bathing spot. A "hot pot" on a tourist map can be too hot or variable.
