The day we went to the lake only one mile of the rim was open but later in the year one can drive the entire 33 mile rim. There are places to pull of to enjoy the view all along the rim drive.
A small volcanic island, Wizard Island, rises 764 feet above the surface of the lake on its west side. A small crater, 300 feet across and 90 feet deep, rests on the summit.
This one is not my photo but gives a better idea of how remote the lake is.
