Jefferson Park via South Breitenbush River?

Trying to plan a weekend to jefferson park for the first time.  Realizing solitude in August will not happen I have seen that the South Breitenbush River Trail is less crowded and it sounds like you can tie it into a loop?

Has anyone done this loop?  What is the mileage?  Where should we camp?

Suggestions?
Directions?
Descriptions?

Any and all info is appreciated.

cheers
