This small-group tour takes you from Reykjavík to Þingvellir, Geysir, Gullfoss, the South Coast, Jökulsárlón, and a natural blue ice cave. Expect glacier gear, super-jeep transport, two hotel nights, breakfasts, and an English-speaking driver-guide. Northern Lights sightings depend on weather and solar activity.

“It was an amazing trip to explore the beauty of Iceland with our tour guide Iskren. I did not know which photo to post, because they were all beautiful. Iskren was professional, he taught us a lot of things about the history of Iceland and made extra stops to enhance our experience. Although we did not see the northern lights unfortunately, Iskren checked every half hour for us while we were sleeping. Thanks to him! Overall, a once in a lifetime experience!”
