Magnificent orca (or killer) whales live in the San Juan Islands year-round, and this is the best place in the world to see them in the wild. You can also spot humpbacks, minkes, gray whales, steller sea lions, and many other species of wildlife. Whale sightings are never guaranteed, but the greatest potential for spotting them is with a professional whale watching and wildlife tour. An added benefit to a tour is that onboard naturalists provide identification, education and stewardship suggestions for passengers. The shorter your stay in the Islands, the more important it is to plan ahead. Booking activities in advance will make your trip run smoothly and you'll be more likely to get your first picks!
