Blue Lagoon Adventure Tours
The spa is located in a lava field in Grindavík on the Reykjanes Peninsula, southwestern Iceland. Bláa lónið is situated approximately 13km (8 miles) from the Keflavík International Airport and 39km (24 miles) from the capital city of Reykjavík. That is roughly a 20 minute drive from the airport and a 40 minute drive from Reykjavík. The Blue Lagoon spa and geothermal complex is clearly visible from any of the usual satellite imagery sources at coordinates (63.880, -22.449).
It is claimed that in June 2007 the Blue Lagoon appeared green, bewildering both residents and tourists of Iceland.
