I am considering a trip to Iceland with my son in mid-February. I have read a lot of the forum posts and got a lot of ideas of what we can do while there. I notice that there is a lot of discussion about organized tours for various sites such as the Northern Lights tour, the Blue Lagoon Tour, the Golden Circle tour etc. Typically I do not take organized tours, finding that I am able to do the activity a lot cheaper on my own. Is there some overriding reason to take the tours in Iceland? Are these attractions particularly difficult to reach on your own? what about the Northern Lights - do we need a tour to increase our chance of seeing them?
