For $7.50 each on foot, we saw a seal swimming, a bald eagle with its fishy catch being harassed by crows, logs aplenty, gorgeous views, and people being blown onto their butts by the wind. It was cold, wet, and wonderful. The wind across the bow was more than hurricane strength, but you can stand just back from the bow and keep an amazing view.
We only rode to Bainbridge and back. We'll try other routes on our next visit.
