Iceland is known as the land of the midnight sun (in the summer) and the northern nights (in the winter). In the winter (November to January), Iceland only gets about 4-5 hours of daylight each day. If you're visiting during this time, be prepared for less vitamin D than you may be accustomed to! In the summertime, on the other hand, it's light nearly all day - although you'll still need a jacket.
Icelandic people are known for being very friendly and courteous, while holding a direct and straight-forward communication style.
Iceland, one of the most eco-friendly countries in the world, is committed to using less plastic. According to the locals, purchasing a plastic water bottle is a touristy thing to do. The tap water is clean and fresh, with no added elements.
One of the top attractions in Iceland is the geothermal pools, like the Blue Lagoon. It's important to note - swimming culture in Iceland is quite unique. Be sure to abide by the rules, such as always showering before entering pools!
