Get up close with the killer whales off Orcas Island, the largest of the San Juan Islands near Seattle, on this guided, 3.5-hour whale-watching cruise from Eastsound. Led by naturalist guides and captains, climb aboard a Blackfish fleet vessel and travel through some of the most picturesque scenery in the Pacific Northwest searching for orca, humpback and gray whales. Along the way, see ocean wildlife in their natural environment, like seals, porpoises, sea lions and otters — plus a wide variety of birds and more. Sightings are guaranteed from April through early September.
