You might also be lucky enough to see a pod of Orca or Killer Whale. These iconic black and white members of the dolphin family can occasionally be seen entering or exiting Eynhallow Sound when they’re passing through Orkney’s waters in search of their prey: seals and bony fish. If you see any cetaceans on your boat journey, please log your sightings with Orkney Marine Mammal Research Initiative
Here is a video created by North Ronaldsay primary school about cetaceans you might see from the North Isles ferries
