Þingvellir National Park is an area of Historic and Geologic wonder for Iceland. It is an area where the Mid-Atlantic Ridge surfaces from the bottom of the Atlantic Ocean and the European and North American tectonic plates meet. You can hike along this boundary line and be in two continents at one time!
From the visitor center there are several trails that lead into the countryside. Take the obvious trail down the ramp and into the gap where you can explore the beautiful terrain, waterfalls and historic sites. You could easily spend an entire day hiking around and having fun. Don’t forget to extend your arms side to side in the gap to touch both North America and Europe at the same time!
