This day will certainly stand out in our memories during this Icelandic expedition. Not for the perfect weather, and not just by Icelandic standards, but also for just how much fun can be packed into a day. The near 24 hours of light was also big help. Starting at Akureyri first thing in the morning we traded the National Geographic Orion for buses and headed inland towards Lake Myvatn, stopping at many investing geology sights along the way. By late afternoon we rejoined our ship, not back in Akureyri but instead further along the coast in the town of Husavik. From there we set sail towards the island of Grimey for the opportunity to see more puffins but also to cross the Arctic Circle, which is conveniently located on the island of Grimey. Not being ones to waste the sunlight and lovely weather we decided that a midnight polar plunge was the perfect way to end this amazing day.
