Made entirely of basalt columns, this natural phenomenon is one of the most unique places to visit in the UK. Located on the shores of Northern Ireland, the place has been declared a World Heritage Site. Interestingly, most of these columns here are hexagonal, however, some of them have five, eight, seven, or four sides as well. It is one of the cheapest places to visit in the UK as you will be charged no fee to visit the site.
