Very safe (IF you don´t fit the category that wants to go “bathing” in Geyser or swimming in Glacial Rivers, etc… ;)). Very often we have people that are not dressed / equipped / trained according to circumstances. We do not have warning signs and restricted areas in Iceland and it is therefore important to use common sense and logic when you go “off the beaten track” by yourself. Taking a stroll on your own on glaciers, in the highlands, is very irresponsible and can put your life in danger. You must understand that the nature in Iceland does give and the nature takes back. The weather in Iceland can change from a beautiful sunny day, into the craziest storm and hail in less than a minute! – Therefore please do stay safe and be aware and respect that this is the land of the Ice and Fire.
NOTE : WHEN YOU VISIT NICELAND IN THE WINTER TIME YOUR STANDARD EQUIPMENT MUST BE CRAMPONS AS YOU WILL BE STANDING ON ICE A LOT OF THE TIME!!! – MOST ACCIDENTS HAPPEN BECAUSE PEOPLE FALL ON THE ICE AT GEYSIR AND THE WATERFALL SIGHTS (SUCH AS GULLFOSS, SELJALANDSFOSS, SKÓGARFOSS ETC…).
