The launch on Hwy 192 with access to Lakes Washington and Sawgrass (and higher if you dare). Lake Washington has a spillway and going downstream is only possible at high water. https://www.youtube.com/watch?v=_MRcYmwi2x0

Looking upstream towards Sawgrass Lake.

The Hwy 50 ramp in the background.

The ramp might be challenging for larger boats and there is no overnight parking.

A warning or, for adventurous cruisers, a notice that fresh meat is available.

Sure enough, right down the road we encountered a large alligator. Run, Beth!

Early September and much of the St. Johns was flooded. Even when there was no wildlife visible, the clouds were sufficiently entertaining.

Some of the "downstream" boat launches. None had overnight parking (or fees). My Navionic card ends at lake Harney, but there is actually over 60 more miles if you are comfortable in shallow water.
The sign is courtesy of the Seminole County Department of Leisure Services. Sounds like a nice job.

The Cameron Wight launch and finger pier on Hwy 46.
