There's no ramp here, but it's an easy carry down to the water from your unload spot - about 20 yards. Put in off a gently pitched gravel bar just upstream of the State Route 108 bridge on the north bank. Stick to the well worn trail or risk exposure to the abundant poison ivy. This is a popular swimming hole for the locals in Summer, but there's usually plenty of room to park and put in.
It's an easy, flat-water float/paddle between forested slopes and river-bottom corn fields with a few gentle riffs and an occasional sweeper to avoid. Fishing for browns and rainbows can be fairly good. You'll pass the Umiak Canoe and Kayak launch area (guided river floats available from them) just downstream at the next bridge. It's a little over 3 miles to a broad rock ledge on the north bank where you can pull out in Cambridge just upstream of the "wrong-way" bridge on State Route 15. A short, steep carry up to the road with a lift over the guard rail - again watch for poison ivy. There's decent parking along the shoulder here to take out, but watch for traffic when turning in and out as it moves pretty fast.
