Iceland is an island nation where there's so much ice, when you ask for a glass of water, they give you a glass of ice and ask you to wait.
Jökulsárlón is a large glacial lake in the southeast, on the edge of Vatnajökull National Park. Boat rides through the floating icebergs are available in the summer months. Nearby, there's a black sandy beach littered with washed ice.
Reykjavik in Icelandic means Smokey Bay because the early settlers saw the steam rising from the ground from the geothermal activity and thought it was smoke. The capital does run on geothermal power. As it's part of Scandinavia, there's the obligatory Viking museum but for a very unusual 45 minutes, there's the Penis Museum. On display is a collection of penises of animals ranging in size from whales to hamsters. The gift shop has some excellent souvenirs perfect for any occasion.
Icelandic food is definitely geared towards the brave with dishes with raw whale meat or fermented shark that was left underground for 3-5 months, it's definitely an acquired taste.
The blue Lagoon is a milky blue geothermal outdoor swimming pool located about 45 minutes from Reykjavik. Set in a vast black lava field, the hot waters are not actually natural hot springs, but a result of the construction of a geothermal power plant nearby. The warm waters are rich in minerals like silica and sulphur, reputed to help with treatments of various skin problems. The water temperature of the lagoon averages 37–39°C. There's tons of silica around available to rub all over yourself, or plaster your face with it.
The Golden Circle
The Golden Circle consists of three beautiful locations in southwest Iceland: Þingvellir National Park, the Geysir Geothermal Area, and Gullfoss waterfall. None of them is further than a two hour's drive from Reykjavík, and thus all three can be visited within a day.
