Glaciers, waterfalls, hot springs, geysers and boiling mud-pots combine to make Iceland one of the most extraordinary destinations for a study of natural history. The country is notable for its austere beauty, singular geology and incredible wildlife, as well as its fascinating history: Iceland is home to one of the oldest parliaments in the world at UNESCO-listed Thingvellir. ACE tours take participants to famous sites such as the Golden Triangle, as well as lesser-known areas to search for flora and fauna up close.
