An question to fellow travelers: I found it quite convenient to visit the blue lagoon from Keflavik. Or from Reykjavik-Blue Lagoon-Keflavik. It seems closer and a beautiful way to end your Iceland adventure before resting in Keflavik the day prior to departure.
Now the question is: When you wen to the blue Lagoon, or if you are thinking of going there in the future:
a. would you go at beginning or at the end of the trip and why
b. would you stay in keflavik before or after your visit to the Blue Lagoon
c. Do you think the Blue Lagoon is a must for every Iceland holiday?
