Location
South Iceland
Haukadalur Valley, Golden Circle
Strokkur is Iceland's most famous active geyser, situated in the Haukadalur geothermal valley just beside the now-dormant Great Geysir. Known for its remarkably consistent eruptions every 5-10 minutes, Strokkur delights visitors with powerful bursts of boiling water that reach 15-20 meters into the air. The name Strokkur means "churn" in Icelandic, perfectly describing the churning action visible in its vent just before each eruption. Watch for the mesmerizing blue bubble that forms at the surface moments before the water column explodes skyward.

Getting There
Strokkur is located in the Haukadalur valley, approximately 100 km northeast of Reykjavík. Drive east on Route 1 then turn north onto Route 35. The journey takes about 1.5 hours on fully paved roads -- no 4WD required. A large free parking lot is available at the Geysir Center, from which Strokkur is a 2-minute walk. The nearest town with fuel and shops is Laugarvatn (25 km). Strokkur is a standard stop on virtually all Golden Circle tours (Þingvellir, Strokkur/Geysir, Gullfoss), making it one of Iceland's most accessible natural attractions. Gullfoss waterfall is just 10 km further along Route 35.
Best Time to Visit
Year-round -- Strokkur erupts reliably regardless of season or weather. June through August: long daylight (up to 21 hours) and mild temperatures (10-15°C), but peak crowds between 10 AM and 4 PM. Arrive early morning or late afternoon. September through October: fewer tourists, cooler air making the steam columns more dramatic. November through February: stunning winter eruptions against snowy landscapes with far fewer visitors. Northern lights are sometimes visible on clear evenings. The Golden Circle roads are maintained for winter driving. March through May: returning daylight with moderate visitor numbers. The eruptions are equally impressive and reliable in all conditions -- 5-10 minutes between blasts, every single day.
