We decided to do a loop from Blue Lagoon back to Reykjavík which took up past this pedestrian bridge between the North American and Eurasian Tectonic Plates. On one side is North America the other Europe and Asia. Eventually many many millennia from now Iceland will be split into two islands. The rift between the two plates separated by 2.5cm per year.
We also stopped at a scenic overlooks on our way to the hotel.
