Travel across wide-open Mosfellsheiði heath to UNESCO-listed Thingvellir National Park. Driving through this rift valley, where the tectonic plates are slowly drifting apart, you’ll cross from one continent to another, stop for photos and pass Iceland’s largest natural lake – Thingvallavatn. Next, tuck into a delicious lunch at either Fridheimar, with its impressive greenhouse agriculture, or Farmers Bistro, famed for mushrooms farming – depending on availability. Then relax in the warm waters and magical atmosphere of the Secret Lagoon at Flúðir, Iceland’s oldest, natural swimming pool. On your return, you’ll see the volcanic landscapes that provide enormous amounts of energy for the country.
