Blesi is one of the main hot springs in the Geysir geothermal area. It is made up of two pools separated by a narrow strip of land – the northern and the southern Blesi.
What makes Blesi special?
Blesi is split into two parts – north and south – which makes it look like two blue eyes, or a pair of glasses. The most interesting thing about it is how different the two springs are.
The southern Blesi is very deep and full of boiling water. The water is so clear that the spring sometimes looks… completely empty and dry.
The northern spring has azure-colored water and is only about 1 meter (3 feet) deep.
Water from the southern eye flows into the northern one and heats it up, which is why the northern eye of Blesi stays at about 40 °C (104°F). After the major earthquakes of 2000, Blesi began to boil intensely. Now, however, it remains dormant.
Even though it is not active, Blesi is well worth a stop while you are in the Geysir area. Two pools side by side and the serene blue color of the water make for a truly fabulous view.
How to get to Blesi
Blesi is part of the Geysir geothermal area in the northern part of the so-called Golden Circle, on Road 35. The springs lie right on the marked path that loops through the field.
We come here primarily to watch the eruptions of the Strokkur geyser. It is worth taking a stroll around the whole field, though, and catching a glimpse of both Blesi and Geysir itself – the once mighty geyser to which all geysers owe their name today.
During your walk, you are also sure to see a few more eruptions of Strokkur.
