The Aurora Borealis - or Northern Lights - is one of nature's most celebrated and most beautiful phenomena. The magical dancing blue and green light is caused by collisions between charged particles in the highest reaches of the earth's atmosphere, but most people watching the display are not thinking about the science behind it. Witnessing the spectacular lightshow is a numinous and unforgettable experience. Visitors to Iceland will be pleased to know that, due to the country's latitudinal position, spotting the Aurora Borealis is commonplace between September and April - just head away from the city lights on a clear, crisp night, and the otherworldly glow in the night sky soon becomes apparent. Although somewhat of a 'routine' display for locals, for tourists the chance of seeing the Northern Lights may well be one of the main motivators for choosing Iceland as a travel destination. There are websites that make predictions on the likelihood of seeing the lights and it may be worth checking these out while planning your travel itinerary. Many of the locals will also be able to offer advice about the best places and times to see the Aurora Borealis. The further away from urban areas you get, the more intense the lights are likely to be.
