05. Giant’s Causeway, Ireland
This is one of the most famous tourist attractions of Ireland. If you wish to visit it, it is located in County Antrim on the northern coast of Ireland. The whole area is a result of volcanic eruptions that occurred more than 60 million years ago. In other words, these rock structures are formed from ancient volcanic eruption, when lava repeatedly flowed and cooled as it came into contact with the sea. At some points, the lava columns are 12 meters high and solidified lava exceeds 28 meters. The whole place looks magical, don’t miss it.
