Myself and a couple friends hiked down into Lake Bonita last Saturday.
It's an interesting area for sure. The land was originally part of the Mount McGregor correctional facility which encompassed over 1,000 acres of land. When the prison closed in 2014 it left a huge area of land that was owned by the state, but was going to waste. In 2021 a little over 7oo acres of the land was transferred to Moreau Lake State Park, and opened to the public. Since that time trails were created that loop Lake Bonita and also go back into the Lake Ann Lean-To.
The land the actual prison facility sits on and all 100 structures are strictly off limits to the public.
But we did gain some nice hiking area with Lake Bonita as the center piece of this 709 acre state run area. There's no camping or hunting allowed in the area, and the lake is said to have some acidic properties. Though some say there's good fishing in the lake. By the sign of all the lures and bobbers hanging from trees and barely submerged logs I'd at minimum say the trees are always biting.
