Night follows day in Iceland just as it does elsewhere in the world, but depending on the time of year you visit how many hours of daylight you enjoy can vary enormously.
In December, the sun barely rises before setting again. In June the sun barely sets before rising again. So take your pick. 24 hours of darkness or 24 hours of light.
My money is on a summer, not least because the midnight sun is a beauty to behold, but then again a snow covered winter wonderland has its charms too especially if you go towards the beginning or end of the winter season annd witness the Northern Lights in all their glory.
Chances are you'll fly into Keflavík International Airport which is about 30km from Reykjavik, the capital of Iceland. It's a small city of about 120,000 people so is very manageable.
There's actually a bus to and from the airport that takes in one of Iceland's must visit attractions,
a geothermal spa called the Blue Lagoon. The temperature of the water there averages averages 40°C (104°F) and as it is rich in minerals it is reputedly good for your skin. So cover your body in the silica mud and enjoy!
Reykjavik itself has a number of geothermal outdoor pools and all of them hire swimming costumes and towels so there is no excuse to miss out.
From hot to cold. The Vatnajökull glacier is located in the south east of Iceland and is Europe's largest glacier. You can try hiking there or just marvel as its glacier lake, Jökulsárlón (located just off Route 1 if you're in a hire car).
Staying in the water, the seas off Iceland are a fantastic place to see whales, dolphins and other marine animals. Trips usually run from April to October and can be booked directly with companies at Reykjavík Harbour.
Iceland actually sits on the juncture of where the North American and European continental plates meet - hence its volcanic landscape. The plates are drifting apart at a speed of a couple of centimetres a year and you can see the dramatic impact of this movement at the Thingvellir National Park. Just remember to mind the gap!
Thingvellir forms part of a "golden circle" of tourist attractions that also includes the Gullfoss waterfalls - Europe's largest by volume of water - and Geysir, the hot spring that is the namesake for geysers the world over.
Although Icelandic is the official language of Iceland, Engish is very widely spoken so you will have no problems on that score.
The one downside is that things tend to be more expensive in Iceland than back home, including accommodation, car hire and food. That said, entry to natural attractions is completely free.
