The Journey Begins in Reykjavik

Most options for this tour include pickup from centrally located hotels or designated bus stops in Reykjavik, operated by Grayline. The morning starts with a 45-minute bus ride from the city to the Bláfjöll mountain area — a peaceful, mountain-laden landscape that sets the tone for an outdoor day. This scenic drive is a bonus for those who appreciate Iceland’s natural beauty even before the adventure begins.

The Approach: Lava Fields like a Moon Surface

Once you arrive at the mountain cabin Breiðabliksskáli, the real excitement starts. Here, a safety briefing and gear up — helmets, harnesses, and other safety equipment are provided. From this point, you set out on a moderate hike of about 45-50 minutes toward the crater, crossing a landscape that resembles a scene from another planet. The lava fields are rugged, with jagged rocks and twisted formations, a testament to Iceland’s volcanic past.

Travelers consistently mention the beauty and eeriness of this terrain. Shafigh notes, “The magma chamber is impressive with a lot of colors and the visibility on the aperture is amazing,” illustrating how the interior’s vibrant look far exceeds expectations. The hike is described as straightforward but uneven and hilly, so sturdy hiking shoes are a must.

Reaching the Crater: An Awe-Inspiring Descent

The highlight arrives when you reach the edge of the dormant volcano’s crater. Here, the guides explain safety procedures before assisting you into a lift that takes you down 400 feet (120 meters) into the volcanic chamber. The descent lasts about 10 minutes, giving plenty of time to soak in the views and anticipate the spectacle inside.

Inside, you’re surrounded by spectacular colors and formations — the volcanic walls are often described as vibrant, with hues of red, orange, and yellow, reflecting the mineral content and cooling lava. Guides are vigilant and knowledgeable, often sharing insights about the volcano’s history and geology. Michelle calls the inside “out of this world,” emphasizing how the visual experience surpasses expectations.
