Activity provider: Reykjavik Excursions by Icelandia

Discover the magic of Borgafjörður, celebrated by Lonely Planet as a top region to visit. From Europe's mightiest hot spring, Deildartunguhver, to the captivating cascade of Hraunfossar and the mystique of Vidgelmir lava cave, embark on an adventure through Iceland's geothermal wonders and rich history.

About this tour

Journey to a realm where the power of nature is palpable! Delve deep into the heart of Borgafjörður, a gem in Iceland's west that drew the admiration of Lonely Planet, earning it a place among the “Top 10 Regions To Visit in 2016.”

Our tour unveils the renowned Silver Circle route, a sequence of remarkable sights that capture Iceland's unique geothermal spirit and rich history. At the forefront is Deildartunguhver, not just a tongue twister, but also Europe's most potent hot spring, gushing out a staggering 180 liters (47.5 gallons) of scalding water every second. This thermal marvel isn't just for show; it warms the homes of Borgarnes, Akranes, and nearby farms. So, if you've taken a shower within a 65-kilometer (40-mile) radius, you've already felt its embrace!

But beyond the steam and heat lies a spectacle of cascading beauty: Hraunfossar and Barnafoss. Hraunfossar, or the "Lava Falls", isn’t a single waterfall but a series of rivulets streaming over a distance of about 900 meters out of the Hallmundarhraun lava field. The waterfalls emerge directly from the ground above blanketed by green bushes, providing a breathtaking view that changes with every season. Nearby is Barnafoss, the "Children's Falls". Steeped in local folklore, Barnafoss's azure blue waters churn and rush through a narrow, rocky gorge, a testament to nature's raw power.

The adventure intensifies as we venture into Vidgelmir, Iceland's largestr lava cave, revealing the earth's secrets. The cave stretches 1,595 meters, revealing a dazzling array of stalactites, stalagmites, and vibrant rock formations. The walls, shaped by ancient eruptions, are adorned with mineral-tinted hues of red, orange, and yellow. This subterranean marvel also hides relics from the past, from bones to artifacts, reflecting Iceland's rich heritage.

Lastly, gaze upon the icy vastness of Langjokull, the nation's second-largest glacier, nestled close to Husafell.

Join us and uncover the magic, history, and power of the Silver Circle. Your Icelandic saga awaits!
