We visited Moran State Park with our three year old daughter. There are numerous hiking trails to enjoy. The highlight is the summit of Mt Constitution. We drove up to the summit and then walked up the Observation Tower for a beautiful view of the surrounding islands. It was gorgeous and well worth the stair climbing!
There is a little store at the summit of Mt Constitution that offers some souvenirs and free coffee and hot chocolate. The items were very reasonably priced.
The park is incredibly beautiful and peaceful. I definitely recommend going to see this if you are on Orcas Island.
To visit the park you have to buy a Discovery Pass ($10 for a day pass).
