One of the most common whale species in Tromso, humpback whales are famous for their acrobatic displays, often breaching and slapping the water with their fins. These gentle giants migrate to the Norwegian coast to feast on the abundant herring, making them a regular sight on whale watching tours Tromso. With a length of up to 16 meters, seeing a humpback leap out of the water is a memory that will last a lifetime.
