First off, you will start your hunt for the Northern Lights with a bit of planning via the Aurora forecast and start your exploration by heading in that direction. You might drive for up to one hour to a good spot and perhaps wait for the lights. At this point, take out the hot chocolate and Icelandic pastries. Also have Icelandic wool blankets on board the minibus to keep you warm while standing outside.
There may be the decision of changing spots, by interacting with other locals as there are many different people outside looking for lights every night. This is of course done to increase the possibilities of finding some Northern Lights. If not, you get to try again upon your availability or the next good forecast.
By traveling in a minibus you get the qualities of a smaller group of no more than 16 people, as crowds are being avoided for the best spot available.
