What is special about Iceland?

Iceland is famous for its natural beauties like Northern Lights, Geysir, Gullfoss waterfall (Golden falls), Faxi waterfall, Kerid, Thingvellir National Park and many more. It is also a cold country. Before two months, I had gone to Iceland with my friends. We travelled and stayed there 5 days. One travel company Go to joy Iceland provided all transportation services to us.
