Crews will be rehabilitating the Cleetwood Cove Trail that leads down to the lake, as well as the Cleetwood Marina, where visitors can access the water and catch boat tours to Wizard Island.

“Due to the extent of work to be completed and short construction seasons, trail closures will be required and are expected during the duration of the 2027 and 2028 summer seasons,” the project page reads. “During this time, no boat tours will be provided and the trail will be closed due to construction and rockfall hazards.”

Those wanting to recreate in the deepest lake in the U.S. will need to schedule a visit soon, before access closes for two years.
