Michael and Marilynn board a Viking cruise ship and tour the Baltic Sea in 2017

The second day we drove way out to the Blue Lagoon.  It is located next to a very large geothermal extraction plant that sends water to the Perlan city hot water plant in Reykjavik.  Icelanders and tourists flock to this lagoon to bathe in the mineral water in hopes of all kinds of cures.  The first site to visit is here.  For a very modern web experience the "official" site is georgous.
