Discover 3 of Iceland's most beloved sights on this Golden Circle excursion followed by a soak in Secret Lagoon in a small group setting. Nature lovers and active travelers alike delight in this adventure to glimpse Thingvellir National Park, Geysir Hot Springs, and Gullfoss Waterfall.

Set out from Reykjavik along the Golden Circle—a scenic route through southern Iceland that covers 190 miles (306 km) of not-to-be-missed phenomena. Your first stop lands you at Thingvellir National Park. This UNESCO-listed monument marks a continental drift between the North American and Eurasian tectonic plates. The shores of the park's Thingvallavatn Lake are also where one of the world's first democratic parliaments was formed.

Snap a few photos at the park before heading to Geysir Hot Springs. Here, walk among the bubbling springs, marveling at their geothermal activity. Don't forget to check out the famous fountain geyser before you leave. Next, travel to Gullfoss Waterfall—rated by some authorities as one of the top 10 waterfalls in the world—and enjoy the packed lunch you brought along.

Finally, visit Secret Lagoon. Once a well-kept local secret, this natural pool hovers right around 100 degrees Fahrenheit (38 degrees Celsius)—the perfect temperature for soaking. Enjoy the magical surroundings and achieve a tranquil state before heading over Hellisheidi pass and back to Reykjavik.
