Cascade Lake and Mountain Lake are the largest interior bodies of water on Orcas Island and both are available for visitors at Moran State Park to explore and enjoy. Boating is an excellent way to experience these lakes’ true majesty and there are several options boaters can utilize. Have a picnic on one of the large islets in Mountain Lake or go fishing in the wee morning hours on Cascade Lake, which is stocked annually by the Washington State Department of Fish and Wildlife.
