Iceland's Geysers: Geysir, Strokkur, and the Golden Circle

Iceland's most famous geothermal area is the Geysir Geothermal Field in the Haukadalur valley, ~120 km (75 mi) northeast of Reykjavík—core of the Golden Circle tourist route.

1. Geysir (The Great Geysir)

The namesake of all geysers worldwide. Historically erupted to 60–80 m. Now largely dormant (occasional minor activity). Earthquakes can reactivate it.

2. Strokkur ("The Churn")

Iceland's most reliable active geyser. Erupts every 5–10 minutes to 15–30 m (50–100 ft). A few meters from Geysir. The star of the show.

3. Surrounding Features

• Numerous hot springs, fumaroles, mud pots (bubbling clay).
• Blesi – beautiful turquoise hot spring.
• Boardwalks for safe viewing; warning signs (water 80–100°C).
