Giant’s Causeway is an unusual natural monument with 40,000 interlocking basalt columns that reach a height of 39 feet. There are always many people here hoping to take a nice photo, which is why one shouldn’t expect to experience any form of solitude when going there. A decent alternative to this site can be found in Russia at Cape Stolbchaty. The Russian analog can boast an obvious advantage — the heights of the columns reach 164 feet.
