From Reykjavik: Golden Circle & Kerið Full-Day Tour

Start this 8-hour Golden Circle Plus tour from Reykjavik and head to a beautiful geothermal town named Hveragerði, which is also known as "the earthquake town" - grab a cup of coffee in an active earthquake location!
Next attraction on the tour is the Kerid (Kerið) volcanic crater lake. Its milky blue water and red slopes create a stunning landscape. 
After looking into "The Eye of the World" we'll be visiting the most famous Golden Circle waterfall - Gullfoss Waterfall, which is considered Iceland‘s most famous and powerful cascade.
