March 2013, air just above freezing, water at bath temperature: the Blue Lagoon is exactly as surreal as the pictures promise. You wade through drifting steam in milky blue water with a lava field at your back and try to remember which direction the swim-up bar was.
Tip from experience: condition your hair before you get in, and accept that your camera lens will fog the moment it smells the lagoon. Pair it with Reykjavik and Geysir for the full Iceland hit.
