Overlooks and Pullouts - Crater Lake National Park (U.S. National Park Service) A morning view from Watchman Overlook. Photo credit Linda Powell. The 33-mile historic Rim Drive circumnavigates the lake. When it is open during the summer and early fall, along the drive are 30 overlooks that were designed between 1931 and 1938. Each overlook highlights a specific view of the lake, a significant geologic formation in the caldera, or an environmental feature such as a subalpine meadow. Some of these stops have exhibits with information about the view.
