About three years ago my daughter and I wanted to take a quick trip to a beautiful place. We chose Iceland. The trip was for four days only but a lot was packed into it. We bathed in mystical waters of Blue Lagoon, saw Thingvellir, looked down into a dormant volcano, went to Gullfaus (waterfall), went to the knitting mills high in the mountains (beautiful area with the morning sun glowing on the snow), saw the Icelandic horse, ate in a local restaurant in Reykeyvik, saw the volcanic stones covered in green moss, saw the geysirs, historic churches, and much more.
We had a wonderful tour guide who told us much history. The Irish blood in Iceland is from the days of the Vikings when they brought Irish wives to the island. It seems they couldn't get wives from Norway or Sweden that would go there because nothing was there at the time but a rugged settlement.
A beautiful country with very educated people, but quite expensive food.
Definitely plan on going back again.
