Ice caving tour on Langjokull Glacier （冰川）
On this Langjokull Glacier tour, explore the world’s largest man-made ice cave. A 20-ton monster truck will take you to the entrance of the cave, located close to the top of the glacier. Then hike through the 500m long ice tunnel with separate frozen halls and admire brilliant blue ice formations. You’ll dream about this ice cave experience for years to come!
Whale watching tour from Reykjavik
Hit the high seas on a Dalvik whale watching tour. Witness humpback whales, blue whales, minke whales and even dolphins! In true Icelandic fashion, you will get the chance to try your hand at sea fishing. Your fresh catch will be barbequed Icelandic-style when the tour ends, the perfect way to wrap up the day.
River rafting （漂流） down Gullfoss Canyon.
Whether you’re an expert or beginner, Iceland’s white waters attract people of all skill levels. Your tour begins at Drumboddsstadir, continues down the Hvita River and ends in Bruarhlod Canyon, located at the foothills of Gullfoss Waterfall. The waters will lead you past a water-carved gorge and over a few steep rapids on an unforgettable adventure of a lifetime.
Old farm hike
On this tour we’ll be aiming for the old abandoned farm at Kleif—watching out for the Arctic wildlife that lives in the area, including reindeer and plenty of birds. Upon arrival, we’ll go on a fully guided tour of the farm and hear stories of how Icelanders managed to survive in this unfriendly place. Finally, we’ll enjoy some warming refreshments at the farm after an educational day in the wilderness.
