Ridgefield Kayak Ramp.  Free parking but a bit of a walk down the ramp to get in. Bathrooms are a bit of a walk down the path.  The entire paddle is about 9.5 miles and can get busy with boat traffic. Biggest concerns is that Bachelor Slough is very tidal influences and needs to be done during Hightide over 1.5 or you could have a long portage. Beautiful paddle with lots of wildlife and awesome birdhouses to check out on Lake River.
