This tour will begin when you are picked up from your hotel in Reykjavík and taken to the Bláfjöll Country Park, which sits just on the outskirts of the capital area. From here, it is just a two-mile easy hike to Thrihnukagigur volcano, where you will descend into the magma chamber of the volcano. At the base camp, your group will be split into smaller parties of 6–7 people.

After being equipped with the necessary safety equipment, you will enter the lift’s basket and begin your descent. Nowhere else in the world can you enter a magma chamber this way. This exciting lift journey toward the center of the earth covers 120 meters and takes about 6-7 minutes.

During your slow descent, the beauty of the magma chamber will become instantly apparent. Intense heat and pressure from Thrihnukagigur’s most recent eruption gave the rocks an incredible texture and coloration. Expect to see smooth walls and bizarre formations in many colors: yellows, blues, reds, oranges, and violets. So vibrant that it’s hard to believe that they could be natural.

It is not just the beauty of the space that will amaze you; it is also the size of it. To give some perspective on the size of the magma chamber, enormous monuments such as Reykjavík’s iconic Hallgrímskirkja church or the Statue of Liberty could easily fit inside it.

Once your descent down the chamber is complete, your guide will let you out of the elevator, and you can explore the volcano. You will spend about 30-40 minutes on the ground of the volcano, during which time you can take as many photos as you want. Your guides will be with you at all times, in the cable lift and on the ground in the chamber.

After your exploration, you will return to the elevator and ascend into the bright, open world. Once you reach the surface, you will have the opportunity to enjoy a traditional Icelandic meat soup or vegetable soup and hot coffee/tea/chocolate.

Finally, you will walk back over the lava field. Again, you will be accompanied by a guide at all times. The bus will be waiting for you in the parking lot, ready to drive you back to your hotel in Reykjavík.
