Beautiful place for whale watching. There are other companies in the area as well or you can try your luck ocean side
If you have the time and transportation this is a beautiful drive across the bridge. It got its name from an early settler in 1792 captain Vancouver who felt deceived by the waterway. Him and his navigator Joseph Whidbey thought it was a bay but it was a deep channel dividing the 2 islands.

Great seafood
Beautiful hike. If you make it to the top there are beautiful panoramic views from the highest point island.
