Discover two sides of Iceland on this 10-day trip. Begin in the Golden Circle, home to Þingvellir National Park, where the tectonic plates meet and go snorkeling in a fissure. Then, explore the waterfalls, black-sand beaches, and cliffs along the South Coast, followed by a day surrounded by stunning glaciers. Next, visit a few notable sites on the way back to Reykjavik, before hopping a bus to embark on the Laugavegur Trek for the next few days. Hike around the landscapes rich with volcanoes, mountains, scenic lakes, and deserts before reaching the iconic Thorsmork Valley. Return to the capital for one last night, and soak in the Blue Lagoon before departure.
