Sometimes called Crystal Caves, the ice caves in the Icelandic glaciers are a truly mesmerizing wonder of nature. This winter tour departs from the south-east of Iceland, so you might need to rent a car or a self drive tour.This stunning crystal cave was created by the force of an ice cap and formed by the glacier meeting the coastline.The ice is highly pressurized and contains no air bubbles which adds to the texture and deep blue colour, which is created by the ice absorbing all visible light except for blue, which is the colour that reflects back to us.Best to visit in winter on a specialised tour as caves like this are unstable and can collapse at any time.
