Snorkeling with Orcas Orca Norway has been offering this opportunity to do swimming or snorkeling with these beautiful animals at each season since 1992. Orcas and Humpback whales have been sighted in large numbers feeding on herring. Orca Norway was the first operator in the word which took part of this unique adventure to swim with orcas. We are the Legend of ORCAS and our crew is the most experienced orca crew in the world. The season is from the end of October to beginning of February.
