3 Days in Iceland Itinerary: See the Best of Iceland

8th July 2023 by Eat Sleep Breathe Travel

it is hard to believe that not long ago, Iceland was relatively unknown. However, due to the popular television series Game of Thrones, the country has become much more widely recognised. When I first visited in 2012, people were more confused than interested. Comparing the Iceland of 2012 to the Iceland of today, it is clear to see how much the country has changed....

What to pack for winter in Iceland

30th November 2017 by The Daily S'elf

Before my first trip there, I had no idea what to pack for winter in Iceland. It just looks so cold, but it was actually the same temperature as Ireland the week I went and I flounce about Dublin all winter (and summer for that matter) in just a leather jacket. Would I need thermals and a base layer? Specialist boots for snow and ice? Ski clothes for snowshoeing? Fancy stuff for going out at night in Reykjavik? I hadn’t a clue. Now, I’m much more confident and ready to share my tips about...
