Welcome to Geysir
The most famous of them all, the Great Geysir has dramatically ejected water for around 800 years. In the year 2000 (after an earthquake), the Geysir erupted more than 120m into the sky. But the geyser goes through dormant periods and at the time of writing it was considered inactive. No matter, the very active Strokkur geyser nearby still performs every five to 10 minutes, typically shooting a sizeable 15m to 30m in height before crashing back into the cavern below. Stand downwind only if you want a shower.
