Sondre Stromfjord it is the largest fjord and over 72 miles long. Sondre Stromfjord was quite unique and exciting to travel through. Around each bend there is always something different to look at and photograph. On some of the mountain ranges tourists can see the lava veins from ancient volcanic lava flows. As sailing further into Sondre Stromfjord, there are many spectacular and unique ice fields that flow from the top of the mountain down into the water.
