Lost Lake is a quiet, comfortable recreation area. There are plenty of spaces to barbecue, good parking in most areas and foot access to the river at many places.
We have taken a 31-foot RV to the park and could easily park along the water in several places.
The restrooms are about what you would expect to find in a public park. (Can be nasty during busy times) There are several and many (most) are wheelchair accessible.
I like this park because it's far enough away to be quiet and close enough to reach with a short drive.
