Geysir is a popular stop on many tourist tours in Iceland. We hired a car during our visit and paid a visit during our stay in November. The area has been active for over 1000 years and contains hot springs, geysers and boiling mud pits. Strokkur is the main attraction here, meaning 'Churn' in Icelandic, it erupts every 5-mintues anywhere between 15 and 40 metres high. It's quite a sight and tends to draw in a crowd - even on a snowy day in November.
There's plenty of free parking on the opposite side of the road along with the Visitor Centre which has all the usual things one would expect; cafe, toilets and shops.
